"Please keep your arms and legs inside the shell at all times." Michelangelo says as April is being carried by him while, Raphael is carrying Vern, and Donatello is carrying Alexis in the sewer drain.
"Satellite imagery shows Shredder's reached the top of Sacks Tower." Donatello says.
"If that's where he's releasing the toxin from-" Leonardo then gets cut off by Donatello.
"It's gonna spread all over the city! We need to break a left!" Donatello says as the group hang a left at a nearby sewer drain.
*Timeskip*
"All right listen up. We gotta find the elevators and get up to the roof. You guys get out of here. Get to a safe distance." Leonardo says as the group arrives in a building.
"No no we can go find Sacks and get our hands on the mutagen as a contingency plan. Just in case... You know." April says.
"I'm with April. We're not going anywhere." Alexis says.
"Thanks for the vote of confidence." Raphael says as he looks at Alexis and April.
"If we don't make it back bring the mutagen to Splinter. It can save his life." Leonardo says.
"Sacks's laboratory's on the 36th floor. I've already disabled the security system. Oh and uh... Good luck!" Donatello says as he, Raphael, and Leonardo go to leave.
"Be careful. All of you!" Alexis says as Donatello looks at her.
"Don't worry. We will. We always are." Donatello says.
"If I don't return remember me April. You can always find me in here." Michelangelo says as he gestures to April's heart before leaving with his brothers.
"You're a couple of complicated chicks." Vern says as he runs off with Alexis and April.
