Jaskier doesnβt have a horse. I mean yeah, technically he has Pegasus but in nw and most fanon media he doesnβt. The man walks at the same pace as a horse every day for twenty years. And Iβm sure Geralt let him put SOME things on Roach, but probably not much. Sheβs Geraltβs horse and needs to carry his things AND Geralt, no one wants her to be over extended with bard stuff. So that means Jaskier carries all his stuff himself which is AT MINIMUM, his lute, notebooks, probably like 3 sets of relatively complex performing outfits and road clothes, all his fancy cosmetic stuff, a bedroll, and his METAL coin money. He also probably has first aid things like bandages and potions, frivolous things like baubles and jewelry, food, water, and probably other bard stuff like spare strings and such.
Yeah, Jask is depicted as traveling without bags but thatβs just not possible. He probably carries his own essentials and as someone who backpacksβ that alone is usually 20+ lbs. WITH modern technology aimed at making things lighter. Thats not counting all the fancy stuff heβs prone to and his career tools. Jaskier is probably hauling like 40-50lbs or more of stuff EVERY DAY while mostly roughing it off the land and keeping pace with a man on horseback. Oh, and this is WHILE SINGING AND TALKING the entire time. Can you imagine this manβs lung capacity? To sing and talk constantly while exerting himself?
This is all to say: Jaskier is strong as fuck and fit as hell. The thing is though, he probably doesnβt even recognize it. Yeah, he probably knows heβs got the muscle and such, but he still is largely perceived as a delicate person. He PROJECTS being delicate. Being fragile and pampered and in need of the finer things. He projects capable, but not strong. This. Is. Hilarious.
Jaskier, having already walked 12 miles at a moderate incline carrying 40lbs of stuff without breaking a sweat (itβs barely past midday): Geralt I am FRAGILE. I cannot POSSIBLY walk through this mud. (Itβs like a 3 ft section) Iβm not a rugged mountain man like you, Iβm simply not BUILT for this!
Geralt, staring at Jaskier whoβs as burly as most Witchers and has walked the path w/o Witcher training for over a decade: hm
