To me it hints that Drilling for the moment isnt center stage anymore but rather just what are these two DUDEs doing here at all.  Bout time to call COLOMBO i have been watching his dectetive movies since i was in diapers and can remember that there was never a case that COLOMBO did not solve, not a one.  If COLOMBO could take JB out for a dinner or even a WHOPPER he could tie JB into a knot and get him to spill all of the beans for us.  It would be smarter to do a "goog" search for COLOMBO and see if he would still like to make another ROARING dectetive movie so that we could get to the bottom of this real fast and then get to the bottoms of the drill holes later!
