Writer's Fallout Shelter

Oohh Good question. I'm not using them in anything currently but the next thing I want to work on will. Not a lot of them, just enough to show why the characters are where they are at the moment in the story.

I'm not exactly sure how I'm going to intergrate them but I was thinking like a dream for one and possibly when he sees the female character something like:

He walked into the room and saw her for the first time in years, his mind took him back to the last time they had spoken (insert flashback here).

But then again I'm not sure because I haven't even started the story yet, just my notes on what I want to do.
