Yoooooo she 100% understands those feels. She's not solitary so much as she prefers very small groups and one-on-one social interactions, but privacy and peace & quiet are VERY IMPORTANT to her too, so she gets it. If Lux ever feels like some quiet company, Grace probably enforces the medlabs as being a serene place as long as no one's actively bleeding or being stitched up, so she's welcome to come hang out and not have conversation unless she wants some. I feel like she'd do something like leave Lux gifts (uhhh knitted scarves or patched uniforms) in the engine room from time to time?
