already itself. Or the Sue has turned the Dalek so it doesn't want to kill anymore.

It could be dangerous for Agents to try and put a Dalek back to his own self (nevermind how they'd do it). The moment it got fixed, it'd start to yell "exterminate!" and fire at the agents.

I'd say: let canon sort this Dalek out. If this Dalek doesn't want to kill anymore, I'm sure there are enough Daleks left that can sort him out on that one.

How to get them there though, and subdue them long enough to get an IV in them? Either character is a one man army by himself, and neither of my Agents is strong enough to even think they can win any kind of struggle against them.

There's also the problem of the fact that canonically it's impossible to cut or pierce the skin of someone in this canon unless your own power level is greater than theirs, especially if they're unwilling to let you.

No, it's not TNG. I lean more towards anime than live action most of the time.
