my headcanon here is that legolas is just BARELY visibly holding it together
since canon tells us that mirkwood elves like to party and are fully capable of passing out from drunk
so legolas is using EVERYTHING HE HAS to fuck with gimli and pretend he hasn’t a clue what it’s like to be affected by alcohol
while inside he’s all ‘sdkla;hgsj you can do this leggles you can do this’
‘don’t think about that time you blacked out from dorwinion wine while naked in the middle of an impromptu archery contest’
‘and all your friends drew orc penises on your face’
‘and when you woke up you were halfway to dale without a clue as to how you got there’‘And especially don’t think about that time you drank so much that the dwarves you were supposed to be watching escaped in the empty barrels of wine.’
‘Dad never let me hear the end of that one’
