i want to be jose so bad, listen to these two first hand.

she doesn't say "but you are like a daughter to me"

hi, anon!

he is referring to threesomes in the sexual sense—i mean, the whole case revolves around two women who are sleeping with the same guy—but not from any kind of personal experience; rather, he's speaking from his professional observations.

basically, he's worked enough domestic homicide cases to know that where sex is concerned, three is often a crowd.

you can tell he has experience with this type of case by the direction he later gives to super dave in that same scene re: checking to see if the vic's genitals are still intact. obviously, he's seen a few of these situations before.

in his view, when people have to share, people get jealous, and when people get jealous, people get dead.

grissom's running theory at this early point in the investigation is that one of the women inside the house killed the man in the garage because she was jealous over the attention he paid the other woman. whether the situation was an honest-to-goodness ménage à trois or a deal where the guy was carrying on sexual relationships with both women separately (either with or without their knowledge), grissom believes it is likely that sex was the underlying motive, and that's what he's talking about.

his observation doesn't really have anything to do with his personal sexual experience at all.
