^ You need to read Creative Couplings
Sorry, but I just finished Creative Couplings
a few weeks ago and I don't really remember Tev being portrayed as unlikable, I think he's mostly just misunderstood by and large. Don't get me wrong, he's pretentious and arrogant, but he's also Tellarite and I tend to think of that as just being par for the course with Tellarites.
If you're talking about the incident with Gomez, I'm still not really sure I see it the way you may be seeing it.
Maybe if you explained your view of Tev a bit.
I honestly thought he was growing closer to the crew, but maybe I've been reading into it something that wasn't there.
