Sam who?

[The Only Real Estel]

I watched TTT the other day and when Aragorn says "He's not alone, Sam went with him." At first Gandalf goes "He did?" Then he nods and has this look on his face like, "oh I should have known better." And then Gandalf nods and goes "He did."

Are you sure about that? I thought it went like this:

Aragorn-"He's not alone, Sam went with him."

Gandalf-"Did he? Did he indeed..."

Followed by something like 'very good'
