About Josy/Maya, there was actually a bit of foreshadowing when, in the park date, MC told Josy that his father taught him man stuff and she said she knew someone who would hate him for saying that. She was obviously referring to Maya. Ironically, it wouldn't be hate she would be feeling for him after all. But we only get that at the second playthru, because we hadn't met Maya back then yet.
Chad being gay isn't that surprising either, with all the bromance between him and Dawe. But is it confirmed already?
And what's the deal with Burke and Isabella!?
