Buffy would be pissed!

I don't think she would be angry, I think she would understand, because she knows him so well and she knows what it is like to be a hero - what a burden it can be, but she would be sad, I think:(

Depends on how long afterwards she remembered. I think at any point she'd be angry, both at having her memories messed with and just the universe for being cruel enough to give her that life then take it away so quickly, but the main thing I think she'd feel is sadness. But I think how angry she was and what reaction to the sadness she had would change over time. If it was closer to when it happened I think she'd be very sad and bitter about it, but if it was further on I think it would be a more resigned sadness. By later in the show she better understood the responsibility to the world she and Angel have, so as sad as she'd be, I think she'd be accepting of the situation and Angel's choice to change back.
I still think at any point she'd be mad at not being given a say in any of it though. She had a right to choose if she wanted to remember, and I think she'd be pissed Angel never gave her a say in any of what he did.

I think Buffy would start to really cry because if she remembered everything all at once it would kind of be an emotional overload. After the crying subsided, I think the sadness would set in but I don't think she would ever be angry at Angel--perhaps at the fates, but not Angel. Buffy would understand about her calling and the greater purpose that she is needed for, also that she does not belong to herself but to the people she helps. I'd also like to add that I really wish Joss would have answered this question for us in a Buffy or an Angel episode!

All of the above?

I think she would be pissed about having her memory played with i know i would

x-missmckena-x That was literally exactly what i thought when i read that, I was like Buffy would be pissed

I say sadness, because I feel she could handle the situation better and not have an emotional breakdown.

She would probably react the same way she did when she found out what was going to happen right before it happened. First she seemed shocked, then she got really angry, then ultimately she began to have an emotional break down and couldn't keep her composure.

I don't think it would be much different. Yes she would be angry that she didn't have a say... but that's the way she was when she first found out also. And within a second she lost the anger and just started to breakdown because she knew that Angel couldn't just let her die, he needed to do something about it- even something as drastic as turning back time- but the situation just sucked big time.

i think she would because she would have to deal with alot of emotions in that moment that she remembered, (anger, happiness, excitement, confusion, sadness) thats alot of feelings to feel at once.

A s7 Buffy would be both happy and sad.
A s6 Buffy would stare at the wall for like 3 hours shoked..sad and empty.
A s5 Buffy first angry then sad.
A s1-4 Buffy emotional breakdown

A lot of those..but in the end, she'd understand Angel did what he had to do to keep her safe and ALIVE. Besides, I think she'd be so sad because he's all she ever wanted.

A bit of everything really (except happiness - why would she be happy?). I think her reaction would mirror her reaction in IWRY itself. She'd be shocked at first, of course, then angry until she realises/remembers the reasoning behind Angel's decision, then she'd be sad and accepting.
