Ok so near the start of the series just after john prototypes the harlequin doll, he gives it a high five. ("Couldn't leave him hanging any longer") should this not have secondary prototyped himself with the doll like how Dave prototyped himself with the crowsprite?

There a couple theories as to why such as sprites may not be able to be prototyped with their player if they’re not dead/dying/doomed (Aradia and Jade were both dead before hand and the Dave that was prototyped was from an alt timeline so he was doomed)

Or that sprites just can’t be second tier prototyped with anything that isn’t dead/dying/or doomed. The only time we see a sprite being second tier prototyped with a non-dead/dying/doomed entity was with Rose’s sprite but that may be an exception since it was still had its kernel at the time.
