While Jen was definitely popping pills, and was an addict, Jade just wants to make herself sick, so Joey will "take care of her". He has already told her there is nothing romantic between them, he is a friend, period. But she wants to keep him close, guilty, etc. Thus the comment that he should not worry, she won't tell he killed Ava. Subtle blackmail.
Yep, and now we have a brother & sister having the hots for a married couple, and telling them. I would say, poor Abby, as her husband seems to lust after another woman, despite claiming to love and adore his wife......while the man she considered a good friend, has declared his love for her, making things awkward.
And then Nicole is going to be facing the same situation, won't she, when the man she considers a good friend declares his love for her (as he claimed to Marlena).
