If there's any question why Susan is my favorite character in
El Goonish Shive,
this appreciation Tumblr post answers it pretty well. (Read the summary at the bottom as well.)
(In panel one, she's on the phone to Nanase; that's one of N's fairy dolls, which Susan has apparently suborned, to the side. In panel two, the guy is a minor character named Matt Cohen, who has asked her out. In the four-panel set, that's Sarah she's trying (and failing) to hug. The last panel features Justin, and is virtual only - Susan doesn't hold hands, nor does she lie in the grass.)
