Was Robert Barone jealous of Raymond because of their upbringing? Did he resent his career success? Maybe. A fan theory suggests Robert might have been jealous for an entirely different reason, though.

Raymond getting to be the one that Debra took her interest in, to me, was the final straw.

God bless you always!!!
