Yeah, cause that's totally why she looked at him. In no way was it a "follow my lead" or "see where I'm going with this?" kind of look.
And that's a perfectly valid interpretation of the character, but it's one with which I disagree.
The cumulative evidence prompts my conclusion that Amy has feelings for the Doctor that go beyond just the sexual: Her long-time fixation on the Raggedy Doctor; her obvious attraction to him; her reluctance to acknowledge that Rory was her boyfriend when he and the Doctor met; her refusal to turn away when the Doctor was nude even though her boyfriend was standing right next to her; references to her having made Rory dress up as the Doctor; her room having been full of Doctor pictures and toys before he returned on the night of her wedding; her deliberate decision to take off her wedding ring when the Doctor returned to her before she knew he'd offer to let her travel with him; her willingness to go aboard the TARDIS when she knew there was no guarantee he'd return her in time for her wedding (as he'd returned late twice already); her look at the Doctor when discussing fancying someone she knew she shouldn't; her reluctance to tell the Doctor about her wedding until faced with imminent death; her referring to her reconsidering who she wanted to be with just prior to her attempt to seduce him.
Now, that's not to say that she's in "true love." One of the things I like about Amy is that she's written like a real 21-year-old, not a fairy tale princess who instantly falls for her One True Love once she meets her Prince Charming. (Or, Doctor Charming, as it were.) Nor do I necessarily think her feelings for him will result in anything beyond the platonic; given that she's been fixated on him since childhood, I think there's a very strong chance that her feelings for him are in fact very unhealthy and not something a relationship could ever be built upon, and I think there's a strong chance that the resolution we'll see to the Doctor/Amy relationship will be that they become loyal platonic friends a la the Doctor and Donna.
But I do think that Amy's feelings for the Doctor, at this period in the season, go deeper than just wanting sex or friendship. I think that Doctor Who Confidential got it right when they played Lady Gaga's "Bad Romance" over their intro to the Doctor/Amy kiss -- "Bad Romance" is a song about being in love with your friend when you know you shouldn't be, when you know that the relationship would be doomed if you were to try to make it more than friendship. That's where Amy is right now, in my view -- she wants to be with the Doctor, but on some level probably knows it would never work and it would be deeply unhealthy. "You and me could write a bad romance."
Now, do you know how to disagree with someone on a character interpretation without insulting them for it, or are you just going to continue being condescending for no particular reason?
She's sick and out of whack. That's what the entire next episode is going to be about for crying out loud; fixing her.
That's also a valid interpretation, but I don't share it. The Doctor didn't call her "sick" or "out of whack;" he's obviously concerned that she doesn't remember the Dalek Invasion, and given his lines about time being re-written and the erasure of memory of the soldiers who walked towards the Crack, I think it's reasonable to presume that there's a link between the Cracks and Amy's lack of memory of the Daleks. And certainly the Doctor thinks there's a connection between Amy, her wedding day, and the Cracks appearing.
But I don't think that that means he thinks that Amy is sick, and I certainly don't think that there's any evidence that her attempt to seduce the Doctor is a symptom of any such illness.
