so I don’t know what Serena is hiding, but she is definitely after something. I really don’t believe it’s anything to do with Eric, personally, rather what Eric has in his possession. Those ridiculous photos of him on the bed??? What was that, unless it was the African artifact shown behind him on the table, and that’s why Serena is always wanting to go to his apartment, and why she asked him the other day what/where are all of those things he had brought from Africa. Maybe something is smuggled into one of them and that’s what Serena is trying to find, but for who??? This so-called source calling Nicole is probably after the same thing, but I think he’s nothing more than an angry ex who followed Serena to Salem because he knows what she’s looking for. JMO, of course. I have no spoiler on this.
