As far as Eli is concerned, it sounds like he will try and help Lani keep secret about the paternity of her child. Don't think Eli wants to screw things up with Gabi like Lani is afraid of losing JJ. But somehow I think Valerie will intervene since that would be her grandchild with Abe.
Or Lani lies to Eli too. I kind of like the twist of Eli confiding in Val. It adds another layer to this story that goes beyond Lani simply lying to everyone. I wonder if she may end up miscarrying though.
