Ginny didn't think it was ever going to get any easier to tell people they were dead at home. No matter how they'd died. "Before I start in on this ... do you really want to know? I'll tell you what I'm comfortable telling you," she said. "But only if you really want to know."
There were things that she wouldn't tell anyone, and things she would only tell to the person they pertained to in the event it ever came up. She ... honestly couldn't see herself sitting down and having a deep conversation with the young version of Snape that was here, but it was awkward as anything knowing what she knew. It hadn't mattered at home because both of them had been dead. Here though ... they were alive and of an age and she honestly didn't know what to think about that.
Realizing she was losing herself in her thoughts again, Ginny pulled herself out and focused on Remus.
