Boys Don't Leave (S01E17)

Tyler arrives at Mark's place, feeling overwhelmed by his new baby sibling who seems to be stealing all the attention. He shows up with his bags, but when Mark opens one, a cat inside bites him. Meanwhile, Vanessa talks to Tyler's parents about the situation, expressing concern that sending him over would be emotionally damaging. On another note, Robin scrambles to create a last-minute birthday gift for her boyfriend, deciding on a picture of herself. Vanessa heads to the office to fix the broken computers, while Mark tries to get Tyler out of the house since he has a date. However, Tyler tags along to the restaurant, where he orders an extravagant lobster, causing Mark to cover the bill for both. At the movies, Tyler sits by himself, and when they return home, he attempts to sleep in Mark's room, but Mark insists he should sleep on the couch instead.
