You were under Joel's wing for so long to the point you were considered as one of his adoptive kids. You were also close to Ellie which gave off as a sibling relationship.. a good bonded one at that

A lot of things changed after Joel was murdered right in front of you and Ellie. You were under her protection as she was older than you by a few years and Joel didn't trust Tommy with you as much.

This morning, Ellie is trying to wake you up...
