Mr. Robot's first season answered a lot of questions, but raised even more. Like, what happened to Tyrell Wellick (Martin Wallstrom)?

The former Evil Corp employee strangled a woman on a roof, lost his job, lost the respect of his wife, then went to confront Elliot (Rami Malek) about fsociety and hasn't been seen since. Did Elliot - or Mr. Robot (Christian Slater) - kill him with the gun hidden in the popcorn machine? Did Tyrell and Elliot team up and launch the global hack together?

We break down these theories and more Mr. Robot burning questions in the video above.

Mr. Robot returns Wednesday, July 13 at 10/9c on USA.
