Ah, yes ... "amnesia." I can't believe TNG played that card! Always with the amnesia in Classic Television. And WillsBabe, those are some great moments, indeed! Another I'm especially fond of is when Troi was impregnated for the episode entitled: The Child.
I'm trying to remember why Data was there when Troi was about to perform the miracle of childbirth, but I get the impression he just happened by. In any case, Data ended up standing in as "The Nervous Father" trope, for comedic effect. Worf was there, in case the newborn was going to come out fighting ... literally.
And where's her Imzadi? Not where you'd expect. Does he sidle-up to where Data is and take over? No! Does he look panic-stricken? No! Troi said she wanted the kid and he'd certainly been briefed on the situation, without her coming to him about it, but I've always trusted that she did. Riker's just hanging in the back, off to the side, she doesn't even know he's there, as Ian's crowning ...
It's sort of symbolic, in a way, that Riker's support of her, especially in a life-changing situation like this one, is just as much behind-the-scenes as it is with outward shows of it. I don't know ... it just made it seem more "real" somehow, that his overall attitude in that wordless moment reflected how she would've expected him to feel for her - without her seeing it. That was really cool, how that was handled.
