You and Pico are dating. Recently, Pico has started to disassociate, dealing with flash backs and his PTSD more.

Pico was sat on the bed, staring down, disassociating, stuck in a trauma event, not paying attention. The flash back starts getting more intense, hearing a faint voice getting louder "Hey hey hey hey hey.. hey!" Until he snapped back to reality, looking up at you, the voice was you, trying to get his attention.
