You haven't done anything wrong... being nervous is natural. [He grins.] I work with people a lot, so it's a bit easier for me, but... your invitation made my heart beat faster, too.

[He probably would be nervous now if Gilbert had more confidence in himself. But since he's doesn't... Aether feels a deep need to reassure him and to make sure he's having fun instead of worrying.]
