reacher saw the dark blue chevrolet and instantly linked it through vincent 's testimony back at the motel to the two men he had seen from dorothy coe 's barn , while simultaneously critiquing the connection , in that chevrolets were very common cars and dark blue was a very common colour , while simultaneously recalling the two matched iranians and the two matched arabs he had seen , and asking himself whether the rendezvous of two separate pairs of strange men in winter in a nebraska hotel could be just a coincidence , and if indeed it was n't , whether it might then reasonably imply the presence of a third pair of men , which might or might not be the two tough guys from dorothy 's farm , however inexplicable those six men 's association might be , however mysterious their purpose , while simultaneously watching the man in front of him dropping his car key , and moving his arm , and putting his hand in his coat pocket , while simultaneously realizing that the guys he had seen on dorothy 's farm had not been staying at vincent 's motel , and that there was nowhere else to stay except right there , sixty miles south at the marriott , which meant that the chevrolet was likely theirs , at least within the bounds of reasonable possibility , which meant that the iranian with the moving arm was likely connected with them in some way , which made the guy an enemy , although reacher had no idea how or why , while simultaneously knowing that likely did n't mean shit in terms of civilian jurisprudence , while simultaneously recalling years of hard-won experience that told him men like this iranian went for their pockets in dark parking lots for one of only four reasons , either to pull out a cell phone to call for help , or to pull out a wallet or a passport or an id to prove their innocence or their authority , or to pull out a knife , or to pull out a gun .
