[The intense haziness Bucky seems to be going through goes so much above some of the general reactions today, not to mention the sort of reaction he knows a man like Bucky prefers to have (he always seems to at least try to hold it together despite the nature of events like this.)
So, if it wasn't obvious already, now Lancelot definitely wants to check on him as he passes by. And perhaps he hadn't missed the figure that was on the battlefield with them not so long ago, the one that Bucky is having so difficult a time sorting himself from now.]
