only to be informed that she hadn't been left anything before it was altered. Trina Echolls Alyson Hannigan plays Trina Echolls, Logan's adopted sister and a struggling actress. She is first mentioned by Aaron in "Clash of the Tritons," who says that she is the only one who will talk to him. Logan asks Veronica to investigate his mother's death, and they discover Trina is staying at the Neptune Grand. The film Trina had been shooting in Australia had not worked out, and she had decided to return home. Trina moves back into the house and gets into trouble with money after borrowing money from her boyfriend, Dylan. She asks Logan for a loan; however, he does not give her any money. Because Trina can't pay Dylan, he beats her to which Logan finds out about after seeing her limp and has a black eye. Once Dylan arrives to talk to Aaron about starring in his movie, Aaron confronts him and beats him. In "My Mother, the Fiend," Trina returns to Neptune as the "Special Celebrity Director" of the school play. During this time, Veronica investigates the case of a baby left in the bathroom of Neptune High during the prom of 1980. She believes Celeste Kane is the mother and wants her to own up to abandoning the child. Veronica eventually discovers Trina was the prom baby and tells Trina the truth, excited at the thought of inheriting some of Celeste's wealth. The next day at school, Veronica and Trina talk when Mary, the deaf lunch lady, begins pointing to herself and then to Trina. Veronica eventually deciphers her sign language: Mary is Trina's biological mother. It turns out then-student Mary had an affair with a teacher, and she left baby Trina at his doorstep. He then left the baby in the bathroom at the prom, knowing they would think it belonged to a student. It turned out the teacher was the current principal, Alan Moorehead. Trina busts him in the middle of a staff meeting in front of all the other teachers, and he is fired. As a result of Hannigan's busy schedule, several of her storylines had to be swapped between episodes. Thomas said that he "loved having Alyson in the show" and had "a lot of fun with her".
