It doesn't take a mind reader to figure out where Steve is going with this fairly quickly. They've discussed the possibility of marriage somewhere down the road and recently enough Maeve knows he has the good sense not to jump into that line of questioning too soon.

That just leaves one other option, she has to figure. He wants them to live together. Without even having to think about it for very long, she knows she wants that, too.

"Yeah?" she asks. Maybe it's dumb, making him actually ask when she's almost entirely certain she knows what's coming, but Maeve wants to hear it. That he wants this, it's something special, and she wants him to ask, she wants those words to exist out in the world.
