So all the way back in act 1, John clearly high-fived the once prototyped harlyquinn sprite, and nothing happened. This clearly contradicts the sprite rule that occurred in the recent updates, with the sprites prototyping with anything they touched (be it alive, object or sprite). Think there was any particular reason John did not prototype with the sprite? Or was it simply a mistake on Hussie's behalf?
I think it was because it was his sprite. We saw Kanaya’s sprite touch her before to. Arguable, Dave was able to prototype into Davesprite because he was a doomed Dave, Jadeand Aradia were able to prototype into Jadesprite and Aradiasprite respectively since they were both dead.
