What are you talking about?, in the very first episode both Connor MacLeod and Duncan know Richie is an immortal when Connor leaves he tells Duncan the boy will need watching, in the episode after this one MacLeod begins to train Richie. Also in the episode "Studies in Light" the immortal Gregor even ask Richie what would he do if he were one of them?, he also stated he wanted to see if Richie were his own man or just MacLeod's shadow. Future Immortals give off the their signal even before they die, not close to death, Duncan also stated in the first episode when he was with Tessa he felt something, and she asked if it were another immortal, and Duncan replied no, it's something else, shortly afterward both Connor MacLeod, and Slan Quince arrive.Duncan took Richie under wing to watch over him, because he knew one day Richie would become an immortal.   See 6 other replies

That would be season3 right of passage, not season2   See 6 other replies

Agreed, I caught it also, pretty cool.
That's one reason why Duncan (season2) hangs out with the 18yr old girl's family.
She is killed in a car crash & becomes (fully) immortal.   See 6 other replies

Alexandra Vandernoot actually asked to be written out of the show. She wanted to be in France full time rather than the half time schedule of the show. Apparently she didn't want to be away from her partner. Were it not for that, they would have kept her in the show.There was lots of opportunity to show Duncan with various love interests through flashbacks.   See 6 other replies

Duncan knew he was Immortal from the beginning. That is why he took him in. Rewatch the pilot, he and Connor both knew Richie was Immortal, thats why Connor says "Someone will have to look after him."   See 6 other replies
