Ok, so some make a great case for Anthony Zacchara...especially with the dialog... also the Letch stuff with Kiki. Now I'm thinking it's HIM not Bill Eckert. One reason that's hard to go there is because it would take like SUPER HUMAN everything to think AZ could be the same physically as Luke. Duke and Faison were more matched. Even O..although heavier was the same size as Anna in height.
Spoilers say NED is the one that says Luke reminds him of someone they used to know. Was he around when Anthony was? He was when Bill was on.
Oy to the VEY!!
IF he is Anthony the following clues will come in: Tending Plants..eating pasta
IF he is Bill Eckert, they'll throw Scotty, Lucy and Kevin in there. He was pals with them-- and there's that newbie coming that could be Sly.
Good Mystery though!
OR of course, we can go with Harlan Barrett--or Caleb the Vampire shape/shifing. LOL.. Let's not go there. OR Faison. I will stop watching if it's Faison. Period. Seriously. I said it.
