Bertram Said to Jane : I need to be on the boat when you catch that fish ...(in saison 5 we know that there is maybe a link with fish with Jason Lennon)
I am many things to many people...(redjohn friends and what they see on redjohn, he help them...)
and in the final of the episode 1 saison 6, we can see in the GPS that P = Partridge and B = Bertram ... S1 = Stiles S2 = Smith H = haffner K = Kirkland M = McAllister and Bertram is not so far than Partridge on the map...maybe he is RedJohn
what do you think ;)
