well- i was thinking more along the lines of the 1st x-over going something like this:
MP and Co are at a site, searching for Jarod-clues; however, the VCTF also show up - called in on a strange case (could be murder, could be something else). MP and Lyle come up with a convincing story to explain away their presence, and agree to help the VCTF on the case if they can.
Bailey and Rachel would check into the backgrounds of the Centre staff - only to find that they all check out (Centre planted information, of course).
The case moves along and somewhere in there, Jarod starts helping the VCTF - maybe he plays 'anonymous' caller or 'confidential' informant to Sam - until Bailey and MP have a talk and she tells him all about Jarod (whom she's claiming is the criminal in this case) and Bailey discovers Sam's conversations with Jarod and declares Jarod the top suspect --
from there - i'm drawing a blank -- the VCTF chases Jarod, but somehow he convinces Bailey that he's not the criminal (probably by solving the crime himself) - tho Bailey's not wholly convinced of Jarod's innocence, he's forced to let him go b/c they now have the real criminal - and the Centre folks run off back to Delaware
(i'll do the 2nd x-over later)
