In a way, Wanda was almost worried that Billy seemed so beyond his years. It wasn't just a wisdom that some people just had, he seemed to have the experience to understand why his methods were better, maybe because someone had done it to him and left him on his own to deal with things.
As he seemed to get to the root of it, his cup settling down, Wanda mirrored it, placing her own cup down, out of the way. Out of danger. No point in getting tea everywhere, it'd be a waste. Related. It wasn't out of this world, not entirely. Although it was kind of out of this world given that they were from quite different worlds. But it didn't strike as an impossibility at all.
Her hand did lower over his, a slight squeeze to the back of his hand as a small smile worked onto her face, somewhat sad but not entirely bad. "Really?" Since she lost Pietro, the last of her kin, she'd felt an odd hole in her chest, nestled in her heart. She and Pietro had come into the world together, just eleven minutes between them. They'd done everything together, looked out for each other, been there through it all. He'd protected her when even her own mind had been the enemy, and then he'd been ripped away brutally and suddenly.
As much as Wanda had made a family with the Avengers, had become something of a surrogate with Clint, she hadn't formed anything close to the connection with Pietro, she knew she never would. "Well, that's a good thing, right?" She didn't know if Billy's Wanda still had her brother, or if she ever had him. But if she had Billy, then at least there was something. Family was important, blood or not.
