Tails crossed

Adora manages to capture Catra during their fight. Except it's not actually Catra.
Adora doesn't know that, and puts her feelings and thoughts of their past and current relationship on the line for a very confused Double Trouble, who is trying desperately to keep their act up.

How long can they trick Adora?
