I was trying not to be dirty-minded this time, but that "Dinah and I have a good thing going" and "be a pal and don't upset the apple-cart" really make me wonder if Ollie thinks Hal's trying to muscle his way back into that menage-a-trois they and Dinah had going in the swinging Seventies. If only Hal had clarified that he meant 'good times and male bonding' and not, y'know, good times and male bonding...
