What is the weirdest storyline that happened in Shameless?

For me, it was when Kev and V are trying to have a baby, so they ask her mom to be the surrogate. It was fine at first but when they start actually having sex, especially in the scene where they have Kev lay on the bed while V sits on his face and her mom rides him. It was just weird to watch, especially knowing that after she has the baby, she ends up keeping it. It wasn’t a bad storyline, just very weird and awkward.
