To her it was a simple offer, borne of friendship rather than anything else, and she didn't really see it as anything that Gendry would ever owe her - she just wanted to help, since that's what she does. It's what she's always done, and considering that this man is only person that remembers the Drabwurld, just like her, in a way she can't forget... It makes her want to keep him a little bit closer. Still, she fights back her arguments, nodding her head.

"Of course, that's fine too," and she smiles. "There might even be a cold snap on the fleet one day and then you'll be glad for the stuffy helmet."
