Gaster was taken aback. He hadn't expected that.
"I'm sorry." He murmured again, hugging Underfell again before mentally reminding himself not to and pulling away again guiltily.
"That's the thing..." Gaster mumbled. He didn't want to put Underfell in a situation he wasn't happy about, but he needed someone to do the job.
"I have a favor I need to ask from you. I understand if you don't want to do it but I can't see any other option. I need you to take my Sans home." He motioned slightly with his hand, drawing Sans close to him before picking the short skeleton up again.
"He's not well. He needs to be inside in the warmth but uh... I've got business to attend to out here." Gaster mumbled, looking in the direction Cambria had disappeared to.
