Yes I do think that Glenn is alive but we probably won't see him until the mid season finale or the next half. Also Taekwondo is a martial arts skill that heavily emphasis's on kicks more then punches.
Like the round house kick, Axe kick, back kick, side kick etc. Molly knows most of those moves. And not to sound sexist because shesa woman shes more agile in those techniques, I actual do have something planned out between Morgan and Molly when they actually compare each others techniques but in a friendly matter. for many people who don't know the type of martial arts that Morgan knows is called Aikido.
