A : AFFECTION. how does your muse show affection?
08 | on affection. lon'qu shows his affection in the things he does for people or in his criticism, lmao. he isn't great with his words and usually bungles it when he tries to be affectionate. he's even worse with pda. like, he'll debate it, then decide it's stupid and then back out. or more embarrassingly, he'll end up half-executing it and then chicken out halfway through so he'd rather just not do it all together knowing what he does know. ( it's worse with any woman because he'll be 10000% more likely to just not even look at you. )
he's not outwardly affectionate intentionally, but he will make a point to go out of his way to do certain things for you that he otherwise wouldn't bother to with other people. like, he'll save you an extra slice of cake or something even though he hates sweets. he'll let you borrow his coat or help you step over a puddle or the like. i do think, also, that he can show his affection through his words if he isn't consciously thinking about it.
exhibit a, in his future past 2 dialogue with inigo:
LON'QU: ......INIGO: Father? Is that you? But...how can you be here? You're dead... Oh no... You've come from the afterlife to collect me, haven't you? I'm finished.LON'QU: ...Finished, you say? If you're that ready to die, I won't bother with any speeches.INIGO: Huh?LON'QU: Inigo... I sentence you to death here and now... Prepare to die.INIGO: Ack! Wait!LON'QU: What's the matter? Come at me. I'll make it painless for you.INIGO: But... I don't want to die...LON'QU: You don't? ...Then don't let me ever hear you say you're "finished." If the afterlife sends someone to collect you, you put that messenger in the ground.
lon'qu speaks similarly with his other potential children. ( i'm quite fond of his dialogue with owain, particularly this line: if you want to keep your friends safe, then fight. live to keep defending them. look at what happened to your father. he died to save you. but he also lost his chance to ever save you again. ) he's not critical aimlessly, but he's also not going to let you put yourself down or give up because the going gets tough / beat around the bush really either. i think he's very much like that in normal contexts as well.
in that, he won't let you talk yourself down or talk in possibilities like they're definites. he's very roundabout, essentially. but, tl;dr he's basically just a very actions-oriented person because he's awkward and doesn't know how to say things straightforward when it comes to expressing concern / affection and pda makes him want to spontaneously combust.
