No sooner had they started walking around than they saw a familiar-looking figure strutting around as if he owned the place. The golden laurel wreath on his hand, and the white sash across the red garment told him immediately who the figure was. Yet, it didn't really narrow down the possible time and location.

"Yo man, is that?" Marcus asked, pointing in the guy's general direction. "The freaking Julius Caesar?"

"Yes, now stop pointing if you want to keep your fingers," Tyson said, quickly slapping Marcus's hand down before he could go and offend the Roman general.

They both did their best to get out of Caesar's way to avoid having to follow whatever necessary conventions were. Luckily, he was too preoccupied with arranging something with one of his soldiers to notice two random guys lurking around.

Once they were well out of Caesar's way and no other important historical figures were in sight, Tyson couldn't help but voice his curiosity.

"How is it that you barely know any historical figures, and yet you are familiar with Caesar?" Tyson asked.

"Dude, Asterix and Obelix, duh!" Marcus said as if that was the most obvious answer in the world.

"Well, excuse me if, for a moment, I thought that you were interested in anything more than modern culture, cinematography, and parties," Tyson mumbled.

"What?" Marcus asked, not fully understanding all of the words his friend used even though he could hear them clearly enough.

Instead of answering Marcus's question, Tyson suddenly stopped, staring straight ahead at the building that he hoped and feared to see at the same time. The large blocks of stone that rose up to more than 100 meters high with amazingly made tapering tiers made no place for doubt in Tyson's mind. They were definitely in Alexandria as the Lighthouse of Alexandria stood proudly before them.

"Nothing. I figured it out," Tyson said, still mesmerized by the ingenuity of ancient civilizations which had none of the conveniences of everyday life and yet were able to make wondrous structures. "We are definitely in Alexandria."

Marcus followed Tyson's gaze and stood motionless, staring at the impressive structure.

"Wow, that sure looks cool. How did the Egyptians make it?" Marcus asked, impressed by the skill and dedication involved.

"Beats me. But the ancient people were clever. I think even the history isn't sure how those from the olden times did so much with so little at their disposal," Tyson said.

He wondered if they would get a chance to get a closer look at the lighthouse. However, he thought it inevitable for the second shoe to drop and rob them of the unique opportunity of appreciating the past.

"Then we are all good?" Marcus asked, feeling better when they knew what to expect of a place.

"Not exactly," Tyson said, shaking his head. "I am still not exactly sure when we are. I remember something about Caesar and Alexandria, but I can't recall exactly what's that all about."

"Hm, while you think, can we go and get some food?" Marcus asked, his eyes lighting up in anticipation. "I bet ancient food is amazing and totally different from what we have."

"Marcus, do you ever think about anything but food?" Tyson asked, exasperated.

He thought that his friend was starting to take things more seriously, but apparently, the memory wipe didn't help matters. Furthermore, Tyson couldn't get angry at Marcus as what happened wasn't entirely his fault.

"Yeah, but I think about food first because it gives me strength to do fun things or to better think," Marcus said.

"I guess that makes sense," Tyson said, making peace. "But before we go on a search for the ancient Egyptians most delicious meals, I need to check something first."

"What is it?" Marcus asked as they continued walking.

"The library," Tyson said.

"Dude, I know you are smart and all that, but now is not the time to relax with a good book. We need to fight for survival! Hunt our prey!" Marcus exclaimed theatrically.

"Can you please tone it down? This way, you are bound to get even Caesar's attention," Tyson said quietly but firmly.

"Oops, my bad," Marcus said, trying to behave normally but looking more like a robot than a regular human being strolling the city.

"I am not going to the library to read but to figure out when we are," Tyson said.

"How are you going to do that? Is there like some book that will tell us when we are?" Marcus asked, bouncing excitedly. "Or even better, a time travel manual?"

"No, I don't think so. And of course, there isn't a manual for time travel. But if my memory serves me right, the Alexandria Library is damaged by fire... was damaged by fire. If we see it and it's not damaged, then I'll know we are here before the fire," Tyson said as his brain worked overtime trying to make all the information fit together.

"And when was that fire?" Marcus asked.

"I have no idea, alright!" Tyson snapped.

Seeing the sad look on Marcus's face, Tyson felt guilty for letting his frustrations get the better of him. However, he couldn't help it. In a way, he was jealous of Marcus, that he got to forget all the hardships they went through before the Alamo. On the contrary, Tyson was stuck with remembering everything, with keeping them safe. It was exhausting.

"I am sorry," Tyson said seconds later, as it was never his intention to hurt his friend. "I just think that once I see the building itself, everything will come to me."

"Oh, yeah, because of that visual thing?" Marcus asked, his expression turning from hurt to curious in a snap of a finger.

Tyson's ability to remember things better if they were connected with images was a well-known thing among them. Upon recalling the picture, he could do so for the text, too.

"Something like that," Tyson said, not in the mood to further explain himself.

Mostly because he had no idea if there was some knowledge in his mind that seeing the library could spark. Sure enough, he had read about ancient Egypt and its most important events. Yet, how much of that remained with him was debatable.

After walking around for a while, they finally reached their destination. It was one of the largest and most important libraries in the ancient world and Tyson could clearly see that it had suffered no damage whatsoever. That meant that whatever events damaged it, they were yet to come and that made sense.

After all, didn't they always end up coming before an upheaval and directly or indirectly causing the said upheaval? Why would Ancient Egypt be any different?

"What's with the sour face? You look like you ate a bag of lemons," Marcus said when Tyson stopped to scrutinize the outer appearance of the library.

"Nothing. I was just hoping that we might have missed the fire," Tyson said.

"How come?" Marcus asked.

"Well, I would at least know for sure that we didn't have any hand in damaging a library of all places," Tyson said. "Anyway, I think I am starting to remember fragments of what happened, what will happen, I guess."

"What is it?" Marcus asked, looking for some excitement.

"Something like Caesar and Cleopatra attack Alexandria. Something like that, I am not sure," Tyson said, squinting his eyes as if he were trying to read his own mind. "And in the chaos, the library somehow ends up catching fire."

Then he stopped talking, trying to think of a date when it all happened, wondering how much time they had left. He wasn't even sure that historians knew the exact date, and yet there they were, needing to stay out of trouble.

"And?" Marcus asked, eager to know more, not being a big fan of Caesar.

"And I don't remember anything else. It's all blank," Tyson said, trying even harder to recall any other details. "As far as I can remember, the library was minimally damaged."

"But who won?" Marcus asked, barely containing his excitement at seeing Caesar defeated.

"I have no idea. Probably Caesar," Tyson said, having no memory of King Ptolemy XIII or the queen.

At that point, he was guestimating almost everything. He didn't like that.

"That's a downer. Why do the bad guys always have to win?" Marcus asked, disappointed by the very idea of Caesar's victory. "Do you know how much he tortures Asterix and Obelix? How annoying he is?"

Tyson wasn't sure if he should slap some sense into Marcus, hit his own head on the library walls, or start screaming while he pulled at his hair. Nevertheless, he chose to try a calm and rational approach.

"Marcus, you do know that Asterix and Obelix are fictional characters?" Tyson asked slowly.

"Yes, of course, but that doesn't make their pain any less real," Marcus responded grimly.

Tyson raised his hands in the air as if supplicating God and started walking towards the town market he caught a glimpse of while they went towards the lighthouse. His patience was almost at an end. However, he hoped his friend would make more sense once he had enough food in him.

Marcus ran along, still full of energy, more than ready to try some new food. After all, he knew no matter where or when they were, food was always there for him.
