As far as Tibor, that dude is deeply involved with his production company and while we only see him on his PC a lot he is busy producing videos I'm sure to try to get that business off the ground. They are actually not bad but I'll bet in that business it is hard as fuck to make it into the big leagues.
If I were him I would teach Linda the business and include her in it a lot more. Show her how to produce, edit, all that shit. Then sit back and watch what she can do. I understand he needs to work his ass off doing his job but it is wrecking his marriage a bit. She is clearly devoted to him to the core but leaving her alone while he works hours trying to start a business is taking advantage of her. Besides, she may surprise him with talents that have yet to emerge.
To me, and I may be wrong, she met him and thought he was a god, and he saw her and said nice tits, I think I'll make them mine. I hate to disparage them in that way, but I see what I see. It is a bit unfortunate because I consider them the most normal people on RLC and I always admired their relationship. But it clearly is not what it was.
