I think TPTB were a little surprised that the Ava Morgan romance seems to be going so well--generating believable heat and some softening of attitudes towards Ava...but of course they don't want to write such a central charactor (historically) as AJ as the murderer....but with Monica on the sidelines and all hte older Q's except Tracy dead, how central are the Qs these days? They need to bring back Ned to run the company since Tracy is too busy worrying about Luke to focus on what we were told was a floundering company. If AJ remembers he's the murderer even though he can't be tried again he will go into a total tailspin. By the way, his remembering stuff that he did while he was drunk while he is drinking--based on real psych research studies having people memorize stuff drunk or sober. What you memorize while drunk you remember better when drunk again later than when sober later.
Anyway, wandering, my point was, I'm sure they meant for Ava to be the murderer--it pretty much has to be one or the other--and now they are stuck. I"m trying to recall if we saw Connie herself write the initials, or if we just saw her hand write them. If the latter they could have been done by yet a 3rd murderer just using her hand.
Thanks for all the tracking down of stuff about Ellie and the embryos (another band name!)! I'm a little disappointed if "Spinelli" just goes to another soap---I was hoping he was serious about trying different types of acting, etc. Of course it might be refreshing for him not to have to play Spinelli -- maybe a non-geek character, although fdrankly he's a bit limited by his looks. And yes, he's in a band with "Jason". Maybe he can get a lot of "outs" in his contract so he can do more prime time guest roles, build his resume.
