Street-brawling is one of Amelia's specialties, which is why the elbow to the ribs doesn't seem to bother her, despite the loud groan of pain. It'll leave a nasty bruise, but it's worth it for her freedom. Her grip on his neck stays tight, though there's a lot of shifting as she tries to fend off any future blows. Plenty of time and space to breathe if he's able to pay enough attention while trying to throw her off.
