Oh, she may be a charming snake, but Kate has made plenty of money over the years, could have started up her own company. Just because Stefano took his company back (which she only held for a short time) is no reason to betray her own son as she did. Justin is Victor's nephew, not his "son". Brady is his GRANDSON, but Victor would never throw them away as Kate just did to Lucas.
I can remember when Victor threw her out after a betrayal of him, by her. She may have initially had to scramble....living out of her car, then in the shelter, then waitressing, but it did not take Kate long to get back up on her feet, running her own company, etc. In fact, she has Mytic, plus Hearth & Home. Right now, she has to have plenty stashed away, stocks in other companies, etc. And heck, she doesn't even maintain a home, or a car....so no expenses for her there.
Just hard to believe she would betray Lucas like this just to get a job there. I just hope Victor, who is always one step ahead of everyone, has a plan. LOL (if he keeps tabs on folks, he has to know what Justin has been up to in Dubai....and Elsa!)
