Such an emotional episode! Tyler, Tyler, Tyler!!!!! The full extent of his deception exposed!
I'm utterly heartbroken for Zander.
Ruth's description:
"He's very clever, very mercurial. He travels light. He leaves no paper trail, no digital footprint."
"He's charming, personable, yet highly skilled. Double phones, double accounts, double life. He defrauded this man of hundreds of thousands of pounds."
What do we think - straight up, cold, clever fraudster/conman, or messed up, genuinely conflicted, sociopath, clever fraudster / conman?
There is no doubt he is a master manipulator and ultimately criminal, but personally I love the tiny bit of ambiguity about whether he actually fell in love with Nina, or wanted to even if he actually didn't, their co-addict connection, and exactly how clear Tyler is in his own mind. Also delighted to watch Damien portray another conflicted (or seemingly) character.
The full extent of his deception exposed!
