@fish-o-cola 's tags on my previous post got me thinking a lot, and it ended up very long for a reply, so I'm making it a separate post:
#it's also very Merlin of him to have not noticed any of the complexity going on with Cleo and Dot's relationship#and to not hear any of the hesitation or caution in Cleo's reply#just 'oh I heard you were in a relationship! congrats!'#two thirds of the plot is sailing right past him and he hasn't even noticed
yeah! like, there's this part too:
Cleo: Theyâre so unbothered now, you know? Totally chill with whatever.
Merlin: Havenât⌠havenât they always been like that? And isnât that a good thing?
Not only has Merlin breezed past Dot's interiority (which, yes, they're very good at hiding their thoughts and emotions, but he was also there for them crying at wearing glasses for the first time, so he's seen that no, they haven't always been like that), but it really serves to highlight the differences in his and Cleo's approaches to their primary relationships.
A huge part of Cleo's character arc has been about finding real connections that aren't based in people-pleasing or toxic positivity. A major turning point in that was when Steve accused her of manipulating and using Dot, and Cleo had to come to terms with an uncomfortable aspect of herself. It caused a lot of tension between her and Dot, but ultimately it was in working through that tension that their relationship strengthened. For someone who dislikes her subconscious tendency to smooth over every bit of interpersonal tension, having a partner who is very suddenly like "yeah, sure, whatever" is probably deeply uncomfortable! And then when she does address this issue with Dot, it goes very well, all things considered, and leads to another breakthrough in their relationship, where they are more open and honest with each other than before.
Merlin, on the other hand, describes his conflict with the Biological Man as him being "so determined to vex me!" and says that "If everyone would just leave him to me to manage, to instruct, to guide, then so much of this could have been avoided!â He is uninterested in letting this be the impetus for their relationship to change and progress. He sees the conflict itself as the issue. Frankly, it's very Guilemoth of him! (derogatory) Much like how we saw Aurelia and Cleo's papa take Cleo's attempts to communicate as personal attacks/pointed accusations to which they must deny responsibility, Merlin takes the Biological Man's assertions of personhood as attempts to replace him and refuses to accept that those feelings come from within him.
He is right that Cleo would be an excellent teacher to him because she has seen both the damage the impulse to paper over conflict has done to her relationships and the benefit that comes from choosing to go against them. She even offered to talk with him about it! She gave him advice! But it's not what Merlin wanted to hear, so he deflected and ignored her :/
