Ah, so Vala will be the voice of reason today. Someone has to do it apparently. Anyway, they're not all thoughts he hasn't had thousands of times before all across his lives and he's told himself that after each new genocide until the words start to lose meaning. The Doctor's eyes raise from the dead Goa'uld in Vala's hand to her face. That smile. It's personal for her, of course. Humans always take it personal and he doesn't blame them. At least they're honest about it.

"Well!" The Doctor gives himself a shake, fiddling around with the tubes and needles that Jamie has brought them. There's loads of that he's had plenty of time to get...well, more familiar with them than he cared too admit. He holds up one. "I'll administer it through injection. It should stay active in your system and take effect once Sobek tries to enter. If he enters. I can't say what long-term exposure to it will do to you."

He knows she's committed. Vala's like Eva in that aspect. Not exactly the sort of woman to do things by halves.

The Doctor begins prepping the solution and the needle, the sonic burning green in the dim lighting until he has a filled needle ready to go.
