For prompt what about, Harry decided to pick up scarcrux and when he wake up instead of come back to his timeline, he is inside baby tom head, not as tom but like.. Scarcrux
Harry waking up trapped inside Tom's head: oh...oh no this is the worst timeline Harry after a three minute freak-out: okay time to psychically parent this child into having a conscience -- Tom, fifteen and contemplating killing his father and family again: hmmmm Harry: *loudly singing Wannabe in his head on repeat* Tom: fuck! fine I won't! just stop singing that muggle trash
GENUINELY I need a lot more of these dynamics
