He probably did, but I'd say he was lucky anyway. Most significant others, no matter how adoring, would start getting a wee bit jealous if their sweetie mumbles the name of another woman in their sleep for a week. Even if he HAD explained in advance, most people would get the green-eyed monster whispering in the back of their minds 'is this just a clever tactic of his so he can cheat on me without me noticing?' Kory, on the other hand, comes from a planet where free love is the general policy, and if you read between the lines here, is actually ENCOURAGING Dick to just go ahead and boff the other woman, so she won't keep being woken up by his gasps in the night. 'You want to boink the hot crazy physic girl? That's nice, dear. Tell me all about it afterwards.' Dick, you shmuck - you're passing up a golden opportunity.
