and as others said for how brilliant this game is, i really do wonder what were his intentios for killing the mc? spoilers below
there was a phantasm bit where it was written that he did love mc? but he'd pretend he didn't so he doesnt have to think about it? i wonder if it was because jude was wearing ethan's "mask" and it was more of a throwback to ethan?....
i think the reason he killed the mc is because she stayed up late and he was afraid she was snooping around? maybe he wanted to throw out the ids, but forgot about it because of adrenaline rush? also he did kiss the mc's corpse....yikes.
