While Carmilla is definitely letting her soft side show in Season 2, I want to direct everyone’s attention to the Season 1 finale kiss.
She’s not smiling before Laura says ‘wow’. Because before Laura reacts, she’s scared. The last person she revealed herself to like this turned against her, and threw her into the dark for decades. And even when she does smile, you can see it’s all nerves.
Note how Carmilla’s face falls for a moment. The way her eyes move down so she can put her hands on Laura’s forearms. That’s not an instinctive ‘i want to touch the person I like’ move. That’s a grip to hold her close, because she’s terrified that Laura could still pull away. She can see the way Laura’s reacting that feelings are reciprocated, but she is still so, so scared.
She retrieved a cursed sword from the bottom of the ocean for this girl, and drove it into the heart of the demon that has been plaguing her for centuries. Came back practically from the dead (again) to finally kiss her, and have that kiss reciprocated.
But she is still so terrified of the idea that Laura Hollis could still walk away.
Carmilla has always been a bundle of PTSD and moral brambles and insecurity issues.
