In the episode with the bank robbery, Morse reminisces about "an angel crossing Carfax!. Was this the same blonde who married the bearded academic in that episode, or a different blonde?
Also, said academic seems to talk about getting married, like it has not happened yet, then refers to his wife whom he wants Morse to check up on.
Or did I mis-hear?
Pretty sure "angel crossing Carfax" was Susan, Morse's ex-fiancee. She broke up with him before he completed his studies at Oxford and he was quite broken up about it. Susan is in the "Dead On Time" episode of the original Inspector Morse" series. She makes an appearance in the brief flashback scene in the Endeavour pilot, when Morse first moves into the rooming house.
The academic was indeed already married. When Morse goes to visit him, he (Morse) says, "the last I heard, you were getting married."
