In the other dimension:

The sky turned green and the clouds swirled around and there was a flash of white light and suddenly 3 Autobots and 1 human fell out of the sky into a park. Bumblebee groaned and checked on Raf who was safely curled up in Bumblebee's servo. He let out a sigh of relief and then Ratchet came over to him after finally getting up and before he could do anything to help Bumblebee, Bumblebee held up Raf to the medic and the Medic looked over the human before saying "he is perfectly fine Bumblebee". Bumblebee gave Ratchet a weak smile and then Ratchet got to work, he couldn't do a lot with the little resources he had but he could clean out the wound. Meanwhile Prowl was watching the two mechs and noticed how different they behaved towards each other. Then Smokescreen woke up and noticed Bumblebee's condition. He quickly got up and stood in front of Ratchet and Bumblebee and transformed his servos into his blasters. "Amazing, they act as if they are more than a team" Prowl said and cautiously approached the 3 mechs. Smokescreen saw Prowl walking up to them so he pointed his blasters at Prowl. Prowl knew this was expected so he said "relax, I am an Autobot too" but Smokescreen lowered his blasters but then put them back up and said "this could be another decepticon trick" but Ratchet said "Smokescreen stand down" but Smokescreen didn't listen. Then a Fire Truck, an Army Vehicle, a Compact car, and a Ambulance drove up and Prowl said "not now" and they all transformed and raised their weapons when they saw Prowl at gun point. "Stand down Optimus said but Smokescreen didn't say or do anything that the prime said and then Prowl said "guys you have it all wrong Smokescreen here is trying to protect his teammates" then Smokescreen said "We're too exposed out here" and Ratchet replied "I know but he is losing too much Energon, I can't move him". Smokescreen sighed and put away his weapons and ran over to Ratchet. When Smokescreen ran over to Bumblebee and Ratchet the others put away their weapons. Smokescreen sighed as he looked at Bumblebee then back to the bots and then he ran over to the bots and asked "can you help us". Optimus nodded his head and said "follow us to our base" and Smokescreen gently picked up Bumblebee and followed the bots and Ratchet picked up Raf and followed the bots, then they saw humans and hid behind a building. "What are you doing" Bulkhead asked and Ratchet said "there are humans" and Optimus said "don't worry they know we are robots from another planet" and Ratchet and Smokescreen gasped but followed the bots. On their way human children awed at the size of Ratchet and Smokescreen and Adults paled at the sight of Bumblebee in Smokescreen's arms. When they reached the base Sari looked up at the new bots in awe but she gasped when she saw the poor scout in Smokescreen's arms. "Oh my god, what happened" Sari asked and the bots shrugged their shoulder and Ratchet said "injured in battle, do you have a med kit" and this world's Ratchet left for a minute and got him a med kit and came back and said "back up and let me work". "No, I have to do this" Ratchet said and took the med kit from this world's Ratchet and started to work on Bumblebee. This world's Ratchet was surprised at the medical expertise that Ratchet had as Ratchet patched up Bumblebee. Even though they didn't know Bumblebee they felt bad for the poor bot.
