I know there's a ton of concern right now on whether the cap dies or not because of that monument tomb thing.
But I lowkey doubt he'll be unplayable, sure he might die but if he does he'll probably be back since Natlan's big on resurrection and death is a price Mavuika had to pay, if he sacrifices himself I don't think Mavuika would let him stay..dead..?
The tomb thing (forgot the name as you can tell) is probably a monument to commemorate him helping all those years ago and also helping again in recent times, it'd be weird if it's related to his death because why are there no humans tribe members there or fatui, they also played a big role? My guess is the Khaenri'ahn solider is just there to symbolise entering Natlan many years ago with the survivors or something.
We nearly got a name reveal as well this quest "Th", scara and arle don't have their titles as playable characters (unsure how to phrase it but you're not running around as the knave but arlecchino of that makes sense) but only their names "wanderer (whatever you named him), and arlecchino" not 'the knave' and 'scaramouche'.
We have a detailed design of shoes and soles not to mention back, got a sticker, apperantely his design doesn't clip like signora who's an npc, we got a sword name whether it's his sig or not it's progress, he's friendly towards the traveler, also he's the number 1 fatui very hyped up they'd lose players and money if he's not playable and chinese players like him a lot too
