Jack takes Sayid to St. Sebastian

Jack takes Sayid to St. Sebastian Hospital and hooks him up to monitors and gives him oxygen. It's worth noting that the oxygen tank is in the red and needs to be refilled. This seems to be mistake with the prop. Anyway, it appears that Jack gives Sayid a shot of adrenaline which wakes him up. Sayid freaks out and tries to choke Jack before he realizes who it is. Sayid immediately asks about where Hurley is, if anyone else is there and if anyone else knows he's there.
