I'm curious of Colin is intentionally helping Gil or unaware that this Gil is still Su's Gil. His line upon letting her go, about her feeling something other than sympathy, seems to imply he might be aware, and the consisten cuts to the camera shows that even if he is aware, he may not be able to say what he means.
The choice to tell Gil about Su's fate also seems unnecessary if he is simply trying to determine her reset state. He knows Su is being abused by fellow inmates, why not ask about saving her from that? Instead he conveniently gives Gil a hint as to what exactly she needs to stop.
Of course, I could be totally reading into things and he really is unaware. Either way, go get your girl, Gil.
