Isaac at the bowling alley: Radio Silence
Radio Silence follows Aled Last, who also turns up in the Heartstopper comics. The show cut Aled and built Isaac in the space he left, so this is Isaac carrying around a book about the guy he replaced. Netflix calls it a tribute. It's also a little like wearing your predecessor's jacket to work.
