How did he know that that wasn’t a clone or a body double or something?
Also did he just leave Jade’s body in the tower back in time when he was still alive, or did he just enter the game in the middle of his life, returned with dead Jade to raise baby Jade, then just die?
Because we still don’t know how the hell he got taxidermied. (or at least I don’t, you the person who already read Homestuck, does)
either way, he still gave a baby a gun, and no amount of “oh I saw her dead 13 year old body a while ago so I know she won’t die yet” isn’t really going to cover it.
