Brianna - Speechless [Outlander] 

There actually is a way out of that hold at 1:03. Of course not everybody know that. I imagine it would have been even less rare for someone(especially a weaker person) to get out of those hold back then sense people had less access to martial arts knowledge. I mean Brianna technically had more access then her father but i imagine she never trained herself and probably only seen martial arts on tv. I been hoping to see someone from the future using modern martial arts but no one has as far as i been watching.
