1. Tex and sister aren't main characters. They are secondary. Sister was seen once in season 13 and that lasted only 5 secs Tex went through 1-5, 7-9 and that's it. Only Tex's helmet was found at the end of season 13.
2. Doc is a different story. He's been in and out of the series since season 5. He reappeared in season 7 as well as tucker. Doc in season 11 was teleported somewhere near the end and didn't reappear until half way through season 13.
Quiz is quite a bit outdated, the freelancer arc shows many male characters without helmets, and many characters faces. I also don't really agree with Church being named Jimmy, he is the director just in Jimmy's body

Just saying
Otherwise finished with 33 secs remaining
Great quiz
Still didn't know that caboose accepted orange juice as payment lol
