quote:
You're forgetting a scene in an earlier episode (and I forget which one) in which he's arguing with Jesse or someone about continuing in the meth business and expressed his regret over selling his share in GM to "pay the rent." They may have been other issues contributing to the decision to leave Gray Matter, but it was his decision.
Actually, he says, "Something happened, I'm not going to get into it for personal reasons, but I took a buyout." It wasn't to pay the rent but probably because of the Gretchen situation.
Now, he still technically chose to take the buyout. But, sometimes a situation has become so unbearable, through no fault of your own, you're effectively forced to choose to leave. I suspect an ugly breakup with your romantic interest, followed by her engaging in a relationship with your partner would be such a situation. It's also possible that Elliot and Gretchen took advantage of Walt by stealing his ip/research or screwing him on the $5000 buyout amount.
