Maybe, Smudge just needs a place to retreat too when kitten shennanigans get too much for him to bear?
Have you tried feeding them both together in the same room (but with a bit of distance between the food dishes) When they associate each other with good things it'll help a lot. What about playtimes? If you can get them both interested in the wand toy playtime that will also encuorage them to play together.
We had all three tearing about the living room last night after their favourite bird thing onna stick. We make sure each of them gets to have a go, so all three can be part of the play.
Smudge and Fuzzums sound lovely.
I can't see the piccies, but I'm pants at posting pictures too, alas.
