For the twin
Dontnod protagonists tend to be fond of talking to themselves, especially if there’s an opportunity for a corny joke. Sam takes this to an extreme by bandying the occasional word with a hallucinatory double, a wellgroomed collegiate sort in a striped blazer and specs who pops up at intervals with enigmatic suggestions and warnings. The doppelgänger sometimes appears while you’re in conversation with flesh-and-blood characters, offering his own thoughts on their agendas. Intriguingly, he’ll also try to dissuade you from following up certain leads, promising that it’s for your own good. Presumably he represents some buried aspect of Sam’s psyche, assuming that Sam is not in fact a buried aspect of his. The odds of a concluding revelation in the vein of, say, Fight Club, seem high.
