It seems that given recent events detailing how the crystals work, Jakob was able to imprint upon the original crystal, which was in the watch up until Julian’s hit and run upon Dani. That would mean that regardless of the loyalty programming to Adrian, any of the girls ensnared by that original watch either during the night of the watch (Erin, Mallory, Marliese, etc) or before (Miriam, Cherry, Echo and Claudia, Dani) still had the nugget of Jakob’s programming baked into the cake. It makes lots of things make more sense in retrospect, particularly Jakob’s trap for Erin in Cherry’s head and Mallory/Cherry claiming that Zenon had become a sort of ‘echo’ of Jakob. It also explains why giving away the repaired watch wasn’t as monumental as it seemed, because if the crystal in the repaired watch was attuned to Adrian, anyone Jakob attempted to program with it would have to contend with that bit of Adrian, just as it seems anyone contending with this new crystal will have to contend with Dani
Thanks for that. It more or less chimes with what I was figuring, although I confess I've long since lost track of the various crystals. I suppose it wasn't confusion on my part so much as disbelief (tinged with horror) that Adrian is going to have to go through the rest of his harem doing this to each of them. Hopefully we'll only have to watch a couple of pages of that before cutting away to a different thread. Sometimes it can be a good thing when that happens.
I'm not sure if we have any reason to believe that the watch was ever used on Miriam though - her mind seemed to be filled only with memories of the pendant crystal being used on her.
