By recalling how he accidentally hurt his best friend and how said friend never forgave him even though it was an accident and (unintentionally) echoing Donatello's earlier line "Some things are just beyond our control", April realized how much of a jerk she's being, and it got through to her because it wasn't someone she'd hated at the time telling her that. So he did have a reason to be here. And besides, while Donnie's crush on April is an interesting story dynamic, I never really expected it to become much more than just a running gag. Someone needed to be the voice of reason. Her growing hatred of the Turtles was beginning to get out of control. Casey was able to act as an objective voice and also allowed her to get the normalcy she was looking for. She was able to have a human friend.

Also, she was able to actually hear Donatello's words and remember the good times with the Turtles through a disinterested third party.
