If he wasn't holding so much of her stuff, Mettaton might have done something exceedingly tactile, like hug Alphys. Since he doesn't have a free hand though, he decides against it.

Like he had with Papyrus, Mettaton finds himself extremely curious how many things were different for Alphys. He couldn't bring himself to inquire any further on the matter though, however, because he wasn't sure he'd like the answer. On the same note, he doesn't really want to answer.

"It's certainly different for me," is all he offers. After an awkward pause, he shakes his head and attempts to change the subject. If he keeps his mind off it, it doesn't matter, right?!

"Anyway, come on!! Let's get a move on, or else we'll miss all the night life! We can talk about home later!!!"
