<Snipped quote by Earnest Evans>

So you are saying Sarah Lyon's is 99? Because it's stated those are two different expedition groups. Sarah was three when the group left.

You said in your background that your character left the bunker with [i]Owyn[/i] Lyons, who was part of the first expedition. Sarah Lyons was born in 2251. The timeline here is completely fucked over.
