I don't want to sound rude but you can see with his looks , his movements ect he has learning disabilities just like Katie
He reminds me of my cousin who is now 24 but has the mental capacity of a 7 year old. He has no concept of time, days of the week etc. He can read and write, but it is the level of a poor 7/8 year old. His speech was very delayed and when he went to a mainstream nursery, they noticed straight away that there was a problem. His parents were very in denial for a long time, and they even fought the nursery on their speculation.
He also reminds me of Alfeh in looks and mannerisms, he also had a lot of problems with his teeth, like they just didn't grow like other people's despite a lot of care. It's like his DNA has a missing element. He looks like a typical lad, but you know he's not if you get me. He was a beautiful baby too.
He has never been diagnosed with any conditions, I'm not sure how to word it, he has just never mentally developed. He could never live alone. He does attend college and have a girlfriend that his parents have encouraged so he is happy. They did waste a lot of time refusing to accept that their child had a lot of additional needs though
I strongly suspect that this is what is happening with Dingle but she's keeping it quiet for some reason
