"So, who is this that I've got trapped in a jar that I almost died to save?" Seán questioned with a tinge of anger in his voice as he stormed off back towards Avenger's Mansion, the symbiote tucked under his arm. 

"In that jar is Dark, the strongest symbiote of them all." Anti answered casually, causing Seán to freeze in his tracks and look into the jar with a frown as he contemplated getting rid of it before getting back to base. 

"You already know that I'm not going to let you destroy him." Anti taunted, causing Seán's temper to flare in response. 

"He was the symbiote that had taken Mark over last time we had to deal with you assholes!" Seán snapped angrily as he continued his trek back to base to get rid of Dark, and hopefully Anti, once and for all. 

"It'd be faster if you used your powers. Oh yes, that's right, you're powerless without your suit and without my help." Anti sneered while Seán strode into the subway and ordered his ticket. 

"Oh shut the fuck up." Seán grumbled sourly under his breath as he sat down on a bench and pulled out his phone, the screen lighting up to show him that he had missed a call from both Mark and Tyler. 

"Tempting, but I think I'll pass thanks." Anti laughed in amusement, Seán rolling his eyes and letting out a long sigh of exasperation as he called back Mark. 

"Hey, where the hell are you? Tyler and I have been preparing the lab for the symbiotes so we can get rid of them for good." Mark answered instantly, his voice tinged with impatience and worry. 

"I kinda don't have my suit since it's back at the base, and Anti's been my only source of power." Seán admitted awkwardly as he rubbed the back of his neck with his free hand. 

"Alright, I'll come and get ya. Where are you then?" Mark offered. 

"In the subway." Seán replied, cursing quietly as Anti advanced out of his skin and started to cover his arm and retake control of his body.

"You okay?" Mark asked worriedly, loud noises audible in the background on his end and his voice sounding slightly breathy as if he was running. 

"I-I'm good, I'll call you back." Seán stammered as he ducked into the bathroom of the subway and locked himself into a stall. 

"What the hell are you doing?!" Seán hissed at the symbiote as Anti slithered down his torso and towards the jar.

"Oh sh-"

Before Seán could stop Anti, the symbiote shattered the jar, releasing Dark from captivity so both symbiotes could escape. 

"I'm sure we'll meet again Seán." Dark stated with a deep chuckle as he and Anti slipped out of the stall and into the sink drain. 

Seán immediately ran out of the bathroom and back up to the surface, Mark already waiting for him in his own car. 

"Anti and Dark are gone." Seán informed Mark hastily, his blue eyes wide in fear as he scrambled into the passenger seat. 

"Wait a minute, Dark too?! God damnit, I'll see what I can do once we get back to base." Mark growled in irritation as he stomped down hard on the gas just as Seán buckled up, causing the car to shoot forward like a bullet. 

Back at the Avenger's Mansion, Tyler was pacing back and forth in the lab as he waited for Mark and Seán to return, the male eager to get rid of the symbiotes and focus on making sure Robin could recover. 

Out of the corner of his eye, Tyler spotted two dark blobs moving through the shadows into the lab and towards him. 

Tyler instantly turned up the thermostat in the room as far as he could to weaken the symbiotes, the heat causing both of them to instantly retreat out of the room by sliding out from under the door. 

"C'mon Mark and Seán, hurry up and get here." Tyler muttered under his breath as he returned the temperature to normal and flipped on the cameras, his brown eyes scanning each camera in search of the escaped symbiotes.
