It's very clearly that Joey has a crush on Annette and can't have the guts to tell her of what he feels about her without Tony knowing.
Besides the professional life, there is much to know and appreciate about her.
When Tony and Stephanie had their turn to dance, Annette had a few Speed pills earlier and asks Joey for more, Joey feels Annette had enough but Annette tells him that she likes them and begs him.
Donna is turning 68 this year.
Joey telling Tony off I think Tony gets too jealous of his friends when they get something good and not him.
Known, Tony never did and Stephanie has no interest in Tony anyways.
