Stargate Atlantis, Season 2

[about going in one of the pods]

Teyla:
But is it safe?

Dr. McKay:
Would I be volunteering to go if it wasn't?

Ronon:
No.

Lt. Col. Sheppard:
Which is exactly what makes it safe enough for me to go.

Dr. McKay:
What?

Lt. Col. Sheppard:
Better to have you on the outside, In case something goes wrong.

Dr. McKay:
It won't.

Lt. Col. Sheppard:
But if it does.

Dr. McKay:
It won't. How many times do I have to say this?

Teyla:
Rodney. Between the two of you, if something were to go wrong, which would be the greater loss?

Dr. McKay:
Well, I've never thought of it that way, but... Hey she's right. You should go.

[Sheppard is almost ready to go in the pod]

Dr. McKay:
...so when you want to disconnect, you'll need to really concentrate.

Lt. Col. Sheppard:
You mean, think it.

Dr. McKay:
I think it will probably take a little more that that, otherwise you'd be popping in out of the thing every time it crossed your mind.

Lt. Col. Sheppard:
So, "There's no place like home"?

Dr. McKay:
If that works for you.
