Meanwhile he slips his arm from Matt's hand, trails his fingers down to Matt's hand and weaves their fingers together. Still functional (to observers) but much less platonic and more obvious. especially staying as close as he is to the other man. "We'll be there soon."

He'll pretend he's not making a list of shit they need to cover, meanwhile.
