Wanda saw and sensed River before she approached, but didn't recognize her as someone she'd talked to on the network until she spoke.
The memory relaxed her; she didn't think River was someone to worry about. At least, not in terms of the things Wanda worried most about, like her powers becoming public knowledge or being pitted against a society that hated her.
She'd liked River, found her interesting to talk to, though a little unsettling -- but it was a comfort to think that next to River, no one would ever notice if Wanda was strange. It might be an unworthy thought, but it also meant that Wanda felt a certain kinship with River.
So she smiled back at River, not at all unhappy to see her, even now when almost anyone else would have set off her wariness. But she could see the shape of River's mind, and then River's comment about the box being rude disarmed Wanda. "I don't like it much right now," Wanda admitted about the box. "But I need it."
As thought thought about the credits she could get for it, she could almost see the beauty in the design of the box again. She blinked, and shook her head.
