[Steve does wonder why Dave brought up Doritos when there are none and then doesn't reply to Clem, but that doesn't stick in his mind long. He just gives a nod with an amused quirk of his lips at Dave's introduction.

His attention is on Elsa again, eyebrows going up a little when she confirms she was the one to make the ice castle he saw.]

That's impressive, Ms. Elsa, very nice of you too.

[He looks at Clem.] Well, I was just seeing if Clementine here wanted to stick around and make a blanket fort.

[Lifting his eyebrows and tilting his head towards the other's, Steve silently asks if she wants to invite them. It's up to her.]
