I was thinking the same surely Jeremy would have tried something even tied to the chair he seemed just too scared and desperate. I get why he didn't kick off while Bonnie was around due to the risk but then could he have fought Damon and Enzo is doubtful and Damon was part of his training and showed him many a time how easy it is for him to outdo the Gilbert hunter. Still a little bit of fight with Enzo would have been better than sitting shaking and almost dying. He felt a little weak in that senario. He showed us when fighting with Vaughn and others that he does have some skills now yet we are not using them to full effect anymore.
