Alexandra?
What relationship did she have with the Bartender?
When he saw her in the fire they both obviously knew each other but im not sure if it was said who they was to each other, wife,gf, sister?
Sounds like they were a couple. I watched the part where the bartender says to samurai guy, that he's going to bed. The SG asks if he has a partner, and BT replies not any more, and then says "she found a better provider".
So wife or GF is the bet.
An interesting movie to watch.
Cheers
