A Tickle War Cheers Up All.

(Disclaimer: This story takes place after the events of Sonic and Surge's first battle, and the Revival of Kit and Surge's Memories and Free Will, which has yet to and/or may never happen; This story is non-canon and should be taken with a grain of salt.)
Synopsis:
After Surge's defeat at the Hands of Sonic, and the return of her and Kit's past memories, she's been feeling incredibly angered. But when Kit tries to cheer her up, things quickly escalate. Thankfully, it's more ticklish than murderous.
