He's been a bit of a dick towards Marisha (and not in a similarly joke-y fashion he is towards Sam, for example), but yeah, he was the worst towards Orion. Don't remember the exact episode(s) or moment(s), but he reeeeeally got impatient with Orion's antics (I think one particularly moment was in Orion's last or second to last episode when they were preparing for something in the city) and acted like a big fucking baby a few times, especially around the time of Orion's last 5-10 episodes. He wasn't, like, "you dumbass, GTFO" to him, not THAT direct, but rude still and might've said something like "oh for fuck's sake", though that might've been under his breath so I'm not sure if Orion even heard it.Agreed Travis ribbs people for funny/stupid shit, but it's always in a jokey / positive manner. Except with Orion of course. With Sam, they'll shittalk each other about football.
Can you give some examples where he just straight up insults someone? I really can't remember anything like that. Maybe making fun of Keyleth's goldfish stunt?
His behaviour kind of soured me on him & Grog as a character altogether for a while. Really started to dislike him as a person, though what he did as Grog was still funny. He just came off as the stereotypical jockey type who lashes out with his patience of a 1 year old. He hasn't been as bad since Orion left but sometimes he's still clearly a bit needlessly harsh/impatient towards Marisha at times. Other people can take jabs at her too but those feel more like "ok, Keyleth, let's hurry things along, get to the point" whereas Travis is reeeeally bad at hiding his frustration towards her. Not necessarily verbally so it's easy to miss unless you're paying attention, but still, I think Travis is easily the worst when it comes to being rude as a person.
