"Fine," is literally the only response Strange gets from Billie. Of course there's no added bonus of explaining what just happened, if only for the smallest, weakest hope that he won't ask about it. In reality, she knows that isn't happening but, damn, let her hope!

In any case, she brushes past him and walks back over to the dead hare the old-fashioned way, without any magic whatsoever. After retrieving it, she'll turn back and eye him again. Now, she doesn't really want to scare Bell again, but since he's here—

"C'mon. You can help me drag the rest of my haul back to Amy's place. The other dead rabbits are in a sack so it shouldn't offend your bunny's delicate sensibilities."

Yeah, that last part is definitely sarcasm, even if only light sarcasm.
