Tyler was released without charge after he was questioned about the murder of Damien's sister.
Damien subsequently kidnapped Tyler, but Tyler escaped.
Now, with Damien receiving treatment for a nervous breakdown, Tyler is turning the screw on Mairéad.

"Yeah, we'll be here too," says Tommy.
"You're cancelling out the noise," says Tyler. "It's good."
