As a result, it was Diana's back that ended up against the thick trunk of that tree, with Thor pressing an elbow against her collarbone to keep her from moving. His arm was otherwise flat across her chest, parallel with her shoulders, and of course their eyes locked again. Where else was he going to look? Not past her at the tree, or somewhere off to one side. Nope, straight into her eyes.
The move hadn't taken much effort, but all the same, he found his heart beating faster as he held her there.
