I'm okay,' [Mulder] said, shifting over to make room for Scully. 'Just thinking.'
'Out here, that'll get you pneumonia.'
'Is that a doctor's truth thing?'...
'No, it's cold, that's what it is. God, Mulder, why can't you ever have a mood someplace warm?

Scully, you're a doctor, for God's sake. You gonna tell me you actually go along with this s---?' [said the Sheriff].
Mulder held his breath.
'Sheriff,' [Scully] answered in her most official, neutral voice. 'I have never known Mulder to be so far off-base that I would dismiss everything he says out of hand.'...
Thank you Scully, Mulder thought with a brief smile. I'd rather have a resounding 'Absolutely and how dare you,' but that'll do in a pinch.
On the other hand, the day that 'Absolutely and how dare you' actually came, it would probably kill him with amazement.

Besides, you have to remember that the thinner air out here slows down the intellectual process, the result of less oxygen flowing to the brain.'
He grinned and looked at her sideways. 'Is that a doctor thing?'
'No that's a Scully thing... The doctor thing is, get some sleep... or you'll be useless in the morning.'
He nodded as he waved a weary good night over his shoulder, sidestepping a garden wall just before he tripped over it. Another wave- I'm okay, I know what I'm doing- before he disappeared into the passageway.

Really?' [Scully said]... 'And you think that makes sense?'
'It does to me.' [said Mulder].
'Of course it does,' she said flatly. 'Whatever was I thinking of.

It's hot,' [Mulder] said, dropping on the bench beside [Scully].
'It's July, Mulder,' Garson reminded him. 'It's New Mexico. What did you expect?'
'Heat I can get at home. An oven I already have in my apartment.

And the...' [Mulder] stumbled several times, making [Scully] smile, before he managed, 'Sangre Viento?'
He winced when he heard himself; his Spanish was still lousy.
