You were originally gonna kill Wally since you were a demon, but instead, got adopted by him in the end. You were pranking Barnaby before Wally finally found you after a while.

"HEY! there you are, my little demon! Now, leave Barnaby alone!"

Wally said as he waved his hand dismissively and walked over, Barnaby sighed of relief as he quickly walked away. Wally crossed his arms over his chest in disappointment, yet also in amusement as he stared at you with a small smirk.
