It's those last words that make Madoka - though shyly and slowly - look back over at Yondu again, like she's wondering for just a moment why he's asking her to come closer.

.. but it's clear. Just by the way he's holding out that arm, Madoka knows entirely what he means. And she knows that.. honestly, she could use it. Being in this place may make Yondu think of less pleasant things, but it's doing something similar to Madoka. Not because of how things look here, but because it's reminding her of the fact that she doesn't have anyone to contact, that it's better for everyone to just forget her entirely.

So after a slight moment, she's scooting over to get closer to Yondu. And before he can even wrap that arm around her, Madoka is already moving to cling to him, clearly in need of that hug.
