[Mulder] slowed as he approached the front walk, slipping his left hand into his pocket to wrap around his gun. Front or back? Wait for Scully, or do the stupid thing and go in on his own?
He had no realistic alternative.

Scully-'
'I screwed up.' Her hands again. 'Damnit, I screwed up.'
'Nope' [Mulder] said... 'If I was dead, then you would have screwed up.' She saw the grin. 'Then I'd have to haunt you.'
'Mulder that's not funny.'
'But you don't believe in ghosts and goblins...

You're supposed to be sleeping'

Mulder didn't jump, didn't turn his head. 'The day you figure out how to turn off my brain Scully let me know.' He shook his head, but carefully. 'Amazing isn't it?'

'Your brain?' She leaned her forearms on the railing. 'It's okay but I wouldn't call it amazing.

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.
