who put this here

Right after being pulled out of the water, she looks very much horrified. This is one of the few times we see her with an expression like this. Though it initially seems to give her the blank slack-jawed expression of something dead or deactivated, on repeat watches it becomes clear that this is an intentional expression. She is in fact afraid and hurt and unhappy here.

Closed-mouth frown when she gets dropped. Almost looks like she's wincing from the rough treatment. You could say the wince effect is just from that eye already being broken, but considering the quality of the animation I'd bet on the animators having been very intentional with the angle of this shot to create the wince effect on purpose.

Our first real confirmation that yes she's entirely aware. She moved her hand over her injured eye intentionally and has turned to look at the people shutting her in here. Her finger also tries to twitch erratically, despite being mostly missing. You could say that this is simply due to the damage, but it's also possible that she's doing this entirely on purpose. Her happy memory with meeting Frankie was when Frankie fixed that same finger. It's entirely possible that she has already recognized Frankie, and is trying to call out for help by imitating that same damaged twitch. "It's me! Remember me! Remember this!"

When the storage unit is opened, she's in the same position. Still very unhappy. But then...

She sees who opened it. She still looks pretty afraid, but this is the first smile we see from her.

A moment later, back to a frown. This is when Andi is trying to convince Frankie to tell security. Guinevere really is completely awake, listening and reacting to everything.

Then Frankie tells her happy memory story, and look at that smile!

"That's right!" Though she can't seem to speak at the moment, Guinevere does seem to intentionally open her mouth with a big smile to play along with Frankie. It's not just Frankie puppeting her here, she's genuinely trying to show agreement.

This one I'll admit I might be reading too much into, but it might also be intentional that she flops over to lean onto her friend here. It could also be the motion of the boat and all, but knowing what we know it's also possible she did it on purpose.

When they're caught. That smile is looking a little afraid now isn't it.

This is probably the tiniest, most blink and you miss it expression of the lot- She is NOT smiling in this one, quick shot. This is when Frankie's boss is trying to convince the two, with both threats and promises of a better life, to give Guinevere up. She seems to be worried that they will do exactly that.

But when Frankie makes it clear her intent to resist, Guinevere is smiling again. A smaller smile, but still a smile.

The obvious sign, the scream. This one was impossible to miss. But it wasn't her spontaneously waking up in time to warn them- she has been awake this entire time.

Once again I think they used the angle and her broken eye intentionally to create this expression. The look is almost satisfied. Maybe because she finally managed a clear communication, maybe because she knows she's done everything she could do in this moment. There's also a slight sense almost like she's bracing for impact, definitely knowing what's coming for her.

She twitches once again here. That's not water damage, she's trying to either warn them that danger is still coming or to get up and defend them.

More twitching here, almost seeming to struggle in Frankie's arms. She might be trying to get up and face Sir Arthur right here and now, or might be otherwise preparing to do it.

This smile looks distinctly afraid to me.

Just before Sir Arthur breaks though, she's twitching and trying to move again- though this one is pretty obvious.

Absolutely no one missed this, but how could I not put the best expression in the entire pilot in here? This girl she is distinctly unhinged. Rad as all heck.

After, she goes from that satisfied smile to this much more vulnerable expression. She can be vulnerable when she's being held safe and close and cozy by her friend here to help her.

One last one, again maybe a stretch- but when she's put down, her head turns towards Frankie. It might just be the jostling of being set down, but it's also possible she's turning to her friend on purpose.
