This is not a good start for actually leaving the flat, but John's never been great at restraint and so is more than happy to take another kiss -- one that's a little rough and just this close to bruising (because, fuck, if they're going out like a proper couple, he might as well start claiming).
It's nothing indecent he finds in Q's pocket and John isn't sure if he's delighted or disappointed. This is all very confusing. Still, once they need to breath he takes a closer look at the box and grins just as stupidly as Q. "I love these little fuckers," he declares, as tactful as ever. But seriously: it's definitely his favorite candy. And they aren't only for old people, ta.
"Quick now," he grabs Q's hand and tugs him out the door. "Before we can't."
