Welp, Rita here's been tagged to be one of the Queen's victims, and I'm picturing three different effects, varying by encounter.

First, there's the wonderful nightmares of all the things that could have gone wrong, back home. Ways Rita could have failed coming to life, seeing her world - in various senses of the word - die horribly and it's all her fault. Most likely, she'll end up cowering in a corner when this hits.

Then, there's the confusing illusions, causing her to not recognize anyone at all - like her old feelings of loneliness. Also paralyzing, but prone to inspiring her to lash out at people on the slightest provocation, just like the other 'useless' people who surrounded her for so long.

Finally, there's that oh no nice worst case of her starting to perceive everyone as monsters - at which point she's liable to out-and-out go on the attack if not subdued.

Any of these could mix in at any time, so people can run into her in any of these situations! If people have other ideas, feel free to share them.
