Serious companions glitch.

[Lumen]

While trying to cure my werewolf problem, I noticed how broken my companion friends have become. I can't open up dialogue with Vilkas unless I'm wanted. I can only ask Farkas to follow me and he's unkillable. I married Aela and her job dialogue still works but if I kill her I can't get remarried. Anyone else having problems similar to this?

You want to kill your wife so you can remarry? Interesting...

Skyrim is full of glitches. I'm guessing you are the only one who has had this particular error. I have also had a glitch in the companions, Vikas would come up and talk to me... and then I'd click to exit conversation... and then he'd come up and talk to me.... again and again. There was no way to get him to bugger off. Had to restart my game. Never had that glitch again, and I doubt anyone else has. Just random errors that occur for difficult to pin reasons. Restart your game, dude. Bugger, hey?

Don't know anything about the first two, but as far as I've seen you cannot ever get married a second time. Many have tried in different ways and I haven't seen any successful attempts.

You can remarry on PC with console commands but it can lead to bugs in the future. If your on PS3 like me, you have no chance.
