Sorry Fionna, but she isn't paying much attention to the latter part because she's on the verge of a flailing meltdown. "What about Katina? Who said something about her? Is she here?" Frantically looking around.

Thankfully, there's no way Katina is here (I checked), so her concern is gone as fast as it appears.

"Not that... I care if she is. She's a grown woman, too, and she can go where she wants to!" So there!
