Asriel Dreemurr

[Asriel doesn't expect Mettaton to follow him to a new planet, after what he's been through. If anything, Mettaton could use the rest... even if that's hard to do at Rinzler's home.

He rubs at the back of his head.]

Y-yeah! I'm sure they'll have it cleared soon enough.

Once it is cleared, do you want to stay with us for a few more days? We can move your body back home, but if you don't want to be alone... I um, I can stay over too if that'd be better.

[Chara and Mettaton both might not be very thrilled at the idea of spending more time in the same living space, which is why Asriel throws out the second option.]
