So who have you sided with in Act 1?

Its a quandary, because in a sense TF knew that Graves would have wanted him to escape if both of them were gonna be sent to the locker. TF was a good bro and we can tell Graves is one hell of a loyal guy 'cause of how pissed he is at TF.

But the act of betrayal without Graves' prior knowledge made it appear more criminal, and hence Graves believed he was betrayed. And TF knows how sucky the locker is.

I'd say TF is still in the wrong but not for the reason that Graves thinks.
