i’m not sure if you mean Window Petra or The Cute Sweater so
Window Petra: say nothing. simply allow Sykes to get the piss startled out of him
Cute Sweater: an afternoon’s worth of intermittent mockery to mask that she also thinks it’s cute
(p.s. i know you are an Erika Liker and i am excited to announce that the next update will have Erika expressions ON EVERY LINE because i finished the sprite ;D)
