Casey, Raph and others in “Unfinished Business”

[runs into the lair, panting] Guys! April! Sewers! Hurry!

Casey, what's wrong?

Are the Foot bots back?

W-we were on our way here, and next thing I know April starts acting freaked out, then runs off! She's gone!

Wait, wait… You just lost April!?

Relax! I'm sure there's a logical explanation. Like she was eaten by a giant sewer snake, or something.

Let's go!
