I guess you can forgive Sue's mum for not knowing all of their names, there are far too many of them!
Joking aside, I'm not convinced she is quite saying Samson. It's definitely something similar, but I can't quite work out what it is. Her accent is quite strong though, so it could very well be Samson! It doesn't sound like any of the other kid's names, that's for sure. What dogs did they have back then? Could it have been a pet?! I know the one they had with Lola, before the Frenchies, was Amber who passed away a few years ago now but I'm sure there were different dogs too when KAC was first filmed.
Expect the tell all book to be released as soon as he hits 18. How I escaped from the Mad House!
