Jon clinging to Helen at times, so scared he’s going to lose her too. It’s less likely she’s a monster and very much not easy to kill. Of course Jon thought the sane of Gertrude who always seemed like a solid fixture in his life.

Probably also doesn’t help that his actual parents died when he was young, and suddenly.

Jon waking up from the few times he gets to have his own nightmares begging Elias not to take his mom away again. Helen reassuring Jon that she won’t leave him, even if she is a liar.

Just Jon having the most trauma.
