Right that he needs to sleep. Right on 'paranoid and squirrelly'. Right, even, that Eggsy might need some light nudging (though not his physical presence, for reasons best kept to the two of them) into resuming his previous patterns.

He drops another kiss on Jack's jaw, brief and chaste; a goodnight kiss.

"Do try to get some sleep yourself, won't you? To pass the time, if nothing else."
