3. After Dora's line of, "I...this is against my better judgement," I now think the Hannelore+Sven date will not end well. Dora does have pretty good judgement, most of the time. [P.S. ADD: Though even bad dates can sometimes have positive results for life experiences.]
This is kinda what I was thinking. Good or bad, if nothing else, I'm hoping this is a character growth moment for both Sven and Hanners. Potentially Dora too.
4. Not entirely certain of why Hanners actually needs Dora's permission to go out on a date with Sven, but it is always heart-warming to see how much Dora looks out for Hanners and how much Hanners looks up to Dora.
This really bothered me. A lot. I get that Dora's got issues, and wants to look out for her friends, and Hanners doesn't want conflict and respects Dora and such, but honestly. We're talking about adults here who, issues or not, should be able to make these choices. This shouldn't relate to Dora's issues with Sven because Hanners met Dora first - she can't be accused of using Dora (though I do see how Dora could still construe it as such).
I think that Dora actually doesn't have a lot of respect for Hanners' ability to "be an adult" or "make adult choices", or whatever. This first showed up when Hanners was gonna go comfort Marigold and Dora was all - "uh no, I think I can handle this better than you", despite Hanners being (apparently) better friends with Marigold.
I mean, sure Hanners doesn't have nearly the relationship experience Dora does, but I think Dora equates that to Hanners entire understanding of the world. Meaning, she thinks that because Hanners is somewhere in the teenager stage of wanting to know about love/sex/etc, Hanners is also in the young child/teenager stage of understanding the world) But Hanners was able to survive with Dora-mom before, and she's shown an awful lot of insight into her friends, and general people dynamics (such as when she called out Marten and Steve).
I think Dora doesn't give Hanners nearly enough credit (as well as giving herself more credit than she perhaps deserves) and on top of that, is so jealous of her brother that she can hardly accept that Hanners is making this choice on her own. Interestingly enough, the way Dora keeps trying to be a mom to Hanners (and to a lesser extent, Marigold) makes me wonder if it's a reaction to her own upbringing - she sees enough of her own naivety in them, and is trying to give them the advice she wished her mother would have given her.
