Aaaaand here's what I've got planned so far, watch out for spoilers!

Love - a memory: He's in his mother's apartment with Liv, fixing the sink as his ma fusses over putting makeup on her. It's all very cute and domestic and they have a moment in the car afterwards as he washes the terrible makeup off her face. (It was really terrible makeup.)

Sorrow - a memory: Imprisonment in the Max Rager basement, stepping forward to protect the other prisoners and knowing that he's never going to see anyone he loves ever again. This dream will end with the needle sliding in, so there's no certainty that Drake is dead and no actual evidence of him being a zombie, the guards will only mention that he's being "cured."

Fear - a hypothetical future: In Hadriel, Hope's brains stop sustaining them and Drake goes into full on zombie mode, a raging starving Romero, and bashes Ephemera's head in.
** This dream I'm gonna require that you discuss with me first if you want your character to see it, since knowledge that Drake is a zombie is a really big deal for him. **
