What, like some kind of secret weapon? Honestly, they could probably use Caboose for that. If Doc left so he could basically be traded out for O'Malley... I don't know how to feel about that. Because I really wish for him to do something other than fight. We have plenty of characters, and plenty of fighters. Hell, they even introduced new soldiers that we got to know, so why not use them? I was hoping that we'd follow them more as they became better soldiers, and I guess they kind of have, but this story arc really hasn't focused on them as much as I thought it would. My point being, if you brought back Doc/O'Malley just to be a fighter: we already have plenty of fighters. And actually, having Doc fight instead of those soldiers just makes their relevance to the plot seem even worse, because a charcter who was gone for more than a season had more impact on the battle than they did, if that's what Doc really turns out to be back for. That's low.

Also, what do you mean he wouldn't have gone crazy by staying in the same dimension? In that case, how does anyone go crazy? People typically only spend their lives in one dimension, and they find ways to go crazy all the same.
