Questions about new episode/general

1. Did the "lightning" incident with Steve happen or not? What does it mean? (Garden Vision)

2. What exactly "unburdened" Cals mother to Sarah what she couldnt bear to hear? I missed that part somehow.

3. Is Eddie the real leader? Again something supernatural happened to him and he gained a vision. Or is it just a rebound process with cult?

4. Why is Cal making out with Melanie Griffith? Mommy issue?

Thoughts?
