Cassie Sandsmark & Hiccup
"Is it?" she asked, genuinely curious. "I don't think dragons are pets, but do you talk to Toothless when you're feeling lonely? Rub his belly? Scratch behind his, uh, wing?" Did dragons even have ears?
"All I'm saying is that it's definitely obvious you guys are super tight, which is way cool. Having someone other than a person is sometimes better than having to be social." Cassie was pretty social by nature, thus a statement like that coming from her could weigh in rather heavily to the right person.
"It's just nice to know there's someone there no matter what."
