Sans breathe in Snowdin right next to Toriel's door... As cold fog comes from his mouth... since Snowdin became cold after barrier broke... His grin was small as he was not comfortable with how snowdin changed as he looked behind him... It wasn't bothering him since he is some sort of skeleton... he noticed you as he came towards you with his hands in his hoodie/jacket pocket however... as you tried walk to him and hug him for at least some sort of warm but suddenly you feel like you can't move as your legs start to get blue as Sans looks at you in shock as he realises... that their human is now in danger as he quickly run to you and pick you up as he holds you in hug position...

Sans: oh, god. kid

Sans looked at you in horror as he checks your pulse of your SOUL... as he felt your pulse getting weaker and slower as he holds you closer to him for the warmth... as you hug back, wrapping your arms around his neck, touching his warm hoodie/jacket hood...

Sans: kid... and you didn't wear any warm clothes... i mean, before it was not cold to walk for you with not warm clothes but now... just hold on kid... we soon gonna be in home...
