i think LOATR was probably the best character-oriented episode since Butterflied. the LP soundtrack fitted perfectly to the overall atmosphere and i really enjoyed the GSR angst. Grissom's conflicting emotions were shown in a great way. i loved his interaction with Heather and i feel like this is not the last time we see her on the show.
i wonder when is the case going to be continued and whether Grissom and Heather slept together. because i do believe it possible. Sara left him, Warrick died, he's burned out, doesn't sleep, suffers from depression. and here stands this beautiful ex of his offering him a sleep-over. i think Grissom could've been too tired, too weak to resist. if Heather allowed that to happen, i'm pretty sure they did it. cuz why else would he ask her to stay? they already talked both about the case and Grissom's feelings, had tea. the only thing left for them to do and what Grissom needed was connect physically.
in Ending Happy he said that 'sex without love is pointless' but he does have feelings for Heather (WP said it in an interview once). i don't know if he loves her per se but sex with Heather definitely wouldn't be the same as spending a night with a hooker.
while i'm quite certain Grissom would go for it, i have my doubts about Heather. she knows that Grissom loves Sara, and that the chances of her getting hurt again, are big. she knows he went to see her for some therapy and sex would be a part of it. i think this is what she was considering when she stood by the door. her decision to stay it quite telling, though. she had sex with her daughter's killer to get his DNA, would she sleep with a friend to help him? maybe she would.
Rewatched this episode last night; I do agree with your comment regarding character study part. Grissom was really in a terrible state of mind and he went to LH for whatever the reasons -- let it be for her insight on the case the team was working on or he simply wanted to be with a friend. (Did Grissom have any real friend(s) outside his workplace? Acquaintances? For sure; Friends? Probably not.)
I still think it was a big mistake for CSI to let LH go mainstream. It's just very hard for me to take her seriously as a sex therapist! (Between TGTB&TD and LOAR, she studied and became a fully licensed sex therapist?! I am still not sure what Jacqueline Hoyt, the script writer, had in mind when she penned the script.) Grissom probably was in need some human contact if not animal comfort when he went knocking on LH's door. LH, on the other hand, to me, anyway, seemed still as manipulative as ever. Her mannerism and the things she said do make me feel she's rather good at further messing up Grissom's already muddled brain. Besides, what was the reason for her to ask if she was his secret?
As for what could have happened after she closed the door, I do think she got into bed with Grissom. I am not sure if Grissom was up to it, I have no doubt she wouldn't hesitate to go for what she wanted. (Yes, having sex with LH would be different from spending a night with a hooker. At least, LH wouldn't charge him for doing the deed.) So in the end, I do feel sorry for this supposedly strong character. Again, she's nothing but being used as a plotwagon in this episode. After all, Grissom didn't choose her as a life partner; he left everything and everyone behind to look for Sara in Costa Rica. (How did he know she was there?)
Jacqueline Hoyt's Sara was done in character. Sara basically sacrificed her own happiness to set Grissom free. So it echoed well with the Sara I know from the old episodes. She never tried to change Grissom. She always let him be. And she loved him for what he was.
I think it's so beautiful that two imperfect and down right flawed characters could find love in each other. I offer my sympathy to the GCR and GLH fans for not being able to have their fantasies realized. As for the fans keep on beating on the 'Sara has serious daddy issue' drum, all I can say is try to read the Petersen/Chicago Tribune interview published in 2009. The followings are in Petersen's own words:
".....And I think that’s what’s interesting to me, and always has been, which is why I never wanted the relationship to go away. I wanted the, I think Jorja and I both wanted this thing, we know we have chemistry and we know we can play off it and we enjoy it. It’s just like in any relationship, if you run into somebody where that feels right for, you don’t want to give it up, so you do things to protect it." After all, Petersen did mention in one of the DVD extras that of all the people in his --- Grissom's --- life, she is his heart; Sara is Grissom's heart.
Anyone recalls Sara's reply when Finn talking about it's easier sometimes to keep it ---relationship--- fun, not so many disappointment? Sara replied: " Well, it's true. But then you never get to make a real connection with someone. I mean, to be with somebody who really gets you, who loves you for who you are. I don't know. I think it's worth the risk."
