I'm glad a PP posted the observation about Ted not knowing about the misspelling of definitely before making the error himself. We have three misspellings now - the OCG on the webchat thing (could that actually be Ted?), the communication with the OCG where he was given pre-prepared statements but chose to go off-piste, misspelling again, and the webchat with Jo in episode 6 (also Ted?).
He revoked the ambush at the depot in s5. Dodgy or what?
He is given £100k in cash and only £50k is found. Why not just hand it back? he can't spend it as it's the proceeds of crime. Do we know how much he gave to Steph? Has it been counted? If he didn't give it to Steph how much does he still have?
I think it's plausible that he's seriously bent (not H level bent) and the only people who know, or suspect, are Kate and Steve.
I think this will be the resolution: Ted will be found to be bent but will still carry on some criminal activity outside the force as a retired bent copper.
It also creates some scope for a further series, with Kate and Steve in situ and investigating Ted.
Jesus, Mary and Joseph!
