I was wondering who played Joanthan and who played Rose and Dad in the Episode A Little Romance.

His name was Brent Collins. He played Wallingford on Another World. I think the dad in that was Billy Barty

I did not know he was on Another World

Yes I liked Wallingford as a little kid, I use to watch Another World with my grandma :) Sadly Brent passed away in the late 80s he suffered from some sort of illness that caused him to have a large growth spurt and because of the enormous stress being put on his body he ended up having a heart attack. He was a wonderful actor.

yes he was a great actor
