It's entirely possible that a small part of the reason Freddy's there is in order to get his sisters to get off his back about socialising more—but also y'know supporting Tony (even if he's trying to ignore the big brotherly instincts of wanting to be >:| at one of his sister's boyfriends). Freddy is perhaps surprisingly familiar with and knowledgeable about the show—like really surprising. But he's the kind of guy who likes having some background noise while he works (some days it's music some days it's TV), and fortunately the magics he's usually working with don't seem to interfere with the TV. He arrives about twenty minutes after six after ensuring for the nth time that Iris was fine, and that his parents were happy to babysit.
It's not long before he grabs a beer, making probably a wise decision to avoid the punch (❤sorry tony), and starts to mingle a little.
