Nothing is going to happen with Melissa.
Oh it will likely happen, the tension is there, we've seen it. If Nyx botches and trolls us though by making it never happen though... WASTED POTENTIAL and 0 Stars for this game, TRULY.
But other topics aside: Thanks to some idiots here assuming that Rachel is the dead one is more of an unknown. Yes, Brooke's comment is indeed suspicious and perhaps is foreshadowing of sorts, however that would be a bit on the nose and too simple for this game that is more mind fuckery than logic.
Honestly do hope for a Throuple of sorts or something to that effect with Layla/Val-Elena in the future. Though given Nyx history and semi shitty choice logic... Get the feeling it will likely be a forced 'CAN ONLY PICK ONE' at some point, even if you play your cards right.
All in all, liked the update, more so Vally lovey.
