Awesome :-)
There's someone else here, someone who doesn't belong here any more than he does. It's not Toshiko, not this time. It's someone he knows from somewhere else - not 1941, not Torchwood - but right now all he's getting is flashes of half an image and it's not quite making sense in his brain. After one fleeting glimpse, he thinks it's John, but that's not quite right either.
Then he catches another glimpse, coupled another surge of familiarity, of a dark-haired soldier heading away down the stairs to the bar. He makes his excuses to the group (getting him a bemused, slightly disappointed glance from the real Captain Jack Harkness) and slips away to trail the departing man down into the bar area.
