The Boyfriend is a pink toy brought by and inflated in her famed red water bottle. He is best remembered as the person who poisoned Lily when she drank his water, dubbed "Boyfriend Water." He is entombed in a ceiling tile at the Rice University southern study room on the second floor, three ceiling tiles away from the doors. The Boyfriend is a frequent topic of conversation among the everchanging title group chat, and he is often considered to be their mascot. He is regarded with love and care, which is why he is tagged as Lil' Sebastian.
