You could be right and Steven KNOWS the paternity tests results are WRONG.
Could be his is NOT saying anything cause he wants Liz away from Lucky and he thinks Nik is a "better" choice for his sister
So Steven is letting the "lie" continue

also thinking about the above spoiler
what if Franco taking Alexis also plays into the huge rift for Jaho
Franco gets some "truths" from the Ho but in the process Ho has her "epiphany"
and she realizes how "dangerous" Jason's life truly is...
and she decides to CHOSE HER FAMILY instead
ho finally understands cause sonny almost kills his own daughter when he is out for revenge
and then cause of Jason , she almost loses her mom

wonder if this will be the "reasons" they use to have ho end it with jason this time around
can see them having ho save face and break up with him
and of course , as we saw the other day, jason will be OK LOL he even was expecting it
