Alex Blake:  Can we rewind for a second ? Is ... is it possible to kill someone in San Diego and then drive two and a half hours up to L.A. and then do it again ?
Dr. Spencer Reid: If you drove a V8 engine with a single plane crankshaft 80 miles per hour in good traffic , you took the I-5 to the _ 405 _ to the 10 east , got off on La Cienega , went right on Washington , north on Vermont , and then snuck up Selma using the back alley , you could do it in an hour , 42 minutes , and still have time for tacos .
Alex Blake: Wow .
Jennifer 'JJ' Jareau: Yeah .
