He is a big Mets fan. He's not a morning person and is always hungry. Mary Anne states that he's a careful shopper when he's in the mood in The Secret Life of Mary Anne Spier.

Jessi notes that Logan’s audition had not gone too well in Starring the Baby-sitters Club!. He spoke his lines in a loud, flat monotone, barely pausing at commas or periods. He seemed to have forgotten the purpose of punctuation. His singing had not been much better. He could carry a tune okay, but that was about all. He kept messing up the words to “Wendy”. Instead of singing, “We have a mother! At last we have a mother!” he sang “We have another! At least we have another!” And for “Wendy’s waiting at the door, we won’t be lonely anymore,” he sang “Wind is wading on the floor, we won’t be lovely anymore.” He ends up getting the part of a pirate and ends up getting kicked out of the play after the director, Mr. Cheney, saw him goofing off during rehearsals. When he shouts mutiny he gets kicked off the play only to rejoin later on probation.
