Well, pain to the point she probably won't actually form long term memories of it, most recently. Before that - adoration, devotion, a sincere desire to give Elana everything - the irrational traumatized part of her brain had been wiggling in the back of her head, making her tense, flip-flopping between fear Elana wouldn't need her anymore if she became a god and fear Elana might take enough to kill her, and it usually takes a while of repetition for the therapy techniques Lace's picked up to really work through stuff like that (rationally she'd known both of those were extremely unlikely, and anyways she'd survive the first and probably she'd arguably survive the second given powerful alt with resurrection, but trauma brain isn't very persuadable with logic and usually only properly shuts up if the scary thing happens without being actually bad).
- She has a very deep hatred for both of Elana's birth parents, and she's extremely satisfied she got to kill them for her girlfriend. Nobody should hurt her Elana like that. Nobody will get away with hurting her Elana like that.
- She has very fond memories of every time Elana's hurt her, a warm hazy love curling through them - of course she enjoys pain in general, with strangers too, but she really enjoys suffering for her girlfriend -
- Falling in love with Elana had been easy, incredibly delightfully so. Lace hadn't been trying to stop it, for one, but her memories echo with every trait she adores about Elana, which as she slid into the early stages of new love had become 'all of them' (she also would like to crawl inside Elana's head and is mostly fond of the reticence because it's an Elana trait, but she recognizes that most people don't find science fictional mind melding the height of romance and also probably her brain expressing love by going 'I want to live inside her skin' is a little bit creepy serial killer-ish; not going to stop her from constantly wanting to be telepathic, though.)
- Lace has numerous complaints about Skyrim but any world containing Elana, any path she can walk beside her girlfriend, is one she's happy to be in -
(Her mind's starting to recover from the constant waves of pain. She's hazy, still, and confused, feeling actually now under-stimulated, like she can't figure out any sensations at all because they're all so incredibly faint.)
