I think Casey served a fairly important purpose here; he was April's voice of reason. 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.
