Lip was so jealous of Fiona

I’m currently re-watching Shameless and I’m at the part where Fiona becomes manager at Patsy‘s and Lip is at the unpaid internship and he was such a hater. Lip couldn’t stand the idea of Fiona being more successful than him because he had a superiority complex and thought he was better than her. He constantly put down each of her ideas or accomplishments. Like when she came home with that FAT check from selling the laundromat and he said nothing. I like Lip but it’s not Fiona’s fault you blew your chance at college.
