I'd just like to preen a bit that it was
moi, way back on the last thread who first said it would all link back to the Boys' Home.
I now think it was Ryan who was killed, possibly shot by Jo. Jo will survive to explain about being brought up thinking that Mr Davidson, who her mother married after she was born, was her father. Until she discovered he wasn't, around the time she joined the police and that was when the OCG got her in its clutches.
Ted is not H and is not corrupt. As has been pointed out many times, he would have a much more comfortable lifestyle to show for it if he was. Sindwani has charged him to sort things before his time's up and, like an ageing knight, he has buckled on his armour once more and sallied forth into battle.
He will succeed in exposing Osborne and others and AC12 will survive under a reinstated Sindwani, to go after Nesbitt. He'll retire in S7, having handed over to... someone.
I'd love Ted to interrogate Nesbitt in the Aquarium. Imagine the dialogue!
