Jesse’s not much of a gamer. Both Hana and Genji know this. But when he says he’s never played StarCraft? That isn’t something they can just let go of. Especially when the entry-level difficulty is so simple that just about anyone could take on the campaigns with relative ease, Jesse you have no excuse.
He ends up falling in love with Raynor and crying a lot about Kerrigan. The highest difficulty he can play on is medium (barely). Hana streams the whole thing. People make compilation videos of all the times Jesse gets emotional during the series.
