Hi there!! It's always nice to see you here! I'm always excited to hear about everyone's playthroughs!
!!! SPOILERS (just in case) !!!
Ohohohoho no no you're not a weenie! But yes, I kinda banked on majority of people playing through True Love before No Love. So I wanted to have Sans only say your name from the True Love playthrough. As a little... reminder so-to-speak =) Or course, if someone went straight to No Love, then it'd just be whatever name was picked then.
