Tina wouldn't be the Auror she was if she couldn't tell Melanie was unconvinced, but nonetheless, she didn't feel the need to explain herself further. It was private affairs and not something she wanted to touch on, much less to the child Newt was fostering. So her features remained as impassable as ever until Melanie says that.

"I'd quite like that," She responds easily, softening. Though, of course, it would be some time before she visited again-- far from what the girl was worried over. "I'm sure Newt's currently back to attending to his creatures right now, but if you would like...?"

She doubts that whatever awkwardness or uncertainties may lie between them now, Newt wouldn't begrudge her speaking to Melanie in his home.
