was he reallythere uncle or didthe kids just call him uncle aurthur why didhe havea crush on mallory?

I remember the early Family Ties episode when Arthur, a long time friend of Steven made a pass at Mallory. It was the only episode Arthur appeared.

Well after that pass at jailbait, not really surprised.

I think he was called an uncle out of respect for the close relationship that Steven had with Arthur.

I thought when watching this storyline:

"Mallory is sixteen and if the Keatonses don't go to the police with what they know, Arthur's next female target could be six"
