Strip 441 - with the drawing from one of your links, Useful. I don't know if you've ever been to a grade school function as an adult, or if you watched the kids as they engage in free time, but little kids can come up with some super exaggerated expressions of emotion. They still haven't fully learned that there's certain ways you don't act and certain things you just don't show. We're all taught to hold emotion in check or to outright lie about what we feel... "Shhh, use your inside voice! Settle down. Don't make that face or it'll stick that way. Apologize now. Like you MEAN it!!" Young children get wild and crazy, that's how they are until we train it out of them or they start trying to conform to "social norms" just to fit in. (Which, to clarify, I don't really think it's healthy to beat down anyone's instinct to react as they feel. That ends up with people second guessing themselves and ending up in bad situations from poor judgement skills, but that's a whole 'nother kettle of fish entirely.)
If you want a truly insane child, I'll introduce you to my ex's son from his first marriage, who at 6 years old got chastised for being rude to his dad. He sat in the back of the car and very quietly and very -purposely- said "I can't wait to grow up so I can kill you."
Strip 469 - Yep, Molly's focusing on labels for Sarah, yet her mom only responds to her statement of leaving with "take a jacket". I know if my 9 year old was using such big and uncommon words like "progressive transgender friend" I'd be stopping her to dig more into the situation and not just blithely blowing it off with a mom-phrase. This tells me that at least her mother isn't very observant or terribly involved in Molly's daily life. Big red flag to me and why I question what (if any) actual good attention she's getting at home.
Strip 471- the 2nd of your drawings, Useful. I generally associate that inner-side upturn of eyebrows to convey a sort of worry, but when coupled with a smile it's earnestness. I might be wrong on that, and really it'd be up to Christine to clarify that emotion as she's the one drawing it. (I'd love to see a pic of Sarah with the same expression and see what people interpret that as, for comparison) Pay attention to Molly's -words- though. "Anything. Anything you wanna do is okay with me. ANYTHING at ALL. I'm just happy to be your FRIEND!!" No where in there does she say "I'm just happy to have a transgender friend". She's not even putting responsibility on Sarah for anything at all, she's happy to be SARAH'S friend.
The girl has the social manners of a drunken water buffalo but it's things like this that make me think she's just lonely, not insane. You project your way, I'll project mine, but for all anyone knows this is going in a totally different direction.
I just hope it continues to be told as our storyteller intends it to be told, regardless of debates.
