this is one of the gunners on the revenge, 20 year glf veteran and still active operative, aaaand he's allie's ex. off the top of my head, i'm thinking they've probably worked together a handful of times over the years/fought together in the war if he was in it but didn't actually connect the dots to each other re allie until they were "introduced" at some point. they probably haven't seen each other in a couple of years or more.
