There was, understandably, a lot to take in, and it didn't help that, just as before, Lexi seemed to have his emotions on a string. Didn't help either that it felt... voyeuristic. It wasn't his place to know what passed between her and this man - if he understood it purely as 'duty', that was enough for him. He didn't need to wonder whether or not Lancelot was merely settling for second-best... because clearly he didn't have feelings for Arthur. Not like the feelings which passed between them, at least. Because there wasn't anything Arthur could provide which he couldn't, and for Lancelot to look so empty, so broken... it had to be a lack. Which turned his head in completely the wrong direction, where he'd found Guinevere, and put two and two together, and... - and he didn't like this flashback nonsense one bit because it was so completely irrational and so overwhelming.
“... I'm still lost” He winced at how loud the words came out, aware that he was breaking the moment again. Maybe that was all he ever did, blunder around, trusting in love, in Lancelot to guide him, when he should have known neither was interested enough to set him right all the time.
