When Benjamin hears his master call for him, he slowly comes out of hiding and makes his way towards where his master and Lucifer are standing with....that other one.

Evan turns when Benjamin gets closer, and the shock on his face is mirrored on Will's. By this time, Jase has moved closer to see what's going on, and when he sees Benjamin and Will standing there, he squeezes his eyes shut then opens them again.

"What the fuck is this shit?" he eloquently says, voicing what some others are thinking.
