Telling Katrina that it has been a long time since Igraine or anyone has always sounded to me that the "anyone" was an indication for "no one", meaning that there was really nobody ever after Igraine.

Since we have never seen Uther even flirting with another woman and when considering his reaction after Igraine's death (the Great Purge and living in depression), it would make perfect sense that he has been living in sexual abstinence the whole time. Some kind of celibacy would be psychologically believable and a self-imposed punishment which would also honour Igraine's memory. Impregnating her led to her death, after all.

I also doubt that Gorlois was at the Northern Plains after Igraine's death. There had been peace for more than twenty years, ever since Arthur was born. Gorlois fighting at the Northern Plains would indicate that there wasn't peace, depending on to what kingdom he belonged to. Even if Gorlois wasn't an inhabitant of Camelot, he was surely allied with Camelot, which is made clear when Uther failed to send troops, resulting in Gorlois' death. So it must have happened before the Great Purge and Arthur's birth.

But I agree that they probably haven't thought it through at that point of time.
