The pair finally gets moving, but not before Jonas can have a little fun teasing Bea first. In panel 11, Bea refers to Jonas as "Soleil"... it's just a part of his last name, not a crazy nickname or anything. Bea personally likes calling people in her group by their first name (calling herself Amverly, calling Jonas by his first name), which is fairly uncommon. She isn't Bea by choice; it's just people doing the more accepted thing by calling her by at least a portion of her last name.
So. Interpret her use of his name in that panel as you will.
Enjoy : )
(on another note, I really need to stop making pages with so many panels >____>" eek. Too much to show, not enough space to show it...)
