He didn't believe Higgs really meant his thank you, but he didn't fight it either. Instead he just shrugged it off, trying to fight the head ache that was slowly getting worse.
He smirked when Higgs joked, and shook his head (slowly). 'Yeah right. I know how much you'd appreciate that at the moment,' he said. 'Or did you forget the scar that covers my chest?'
He leaned back in the sofa, letting Higgs cover up. 'Seriously, mate, if you need anything just tell me so. I know how boring it is to just lay around doing nothing.'
