Life imitates art? The path of JM mirroring AF?

So, the Kings said that in the end, Alicia-to an extent- became more like Peter....selfish, a little drunk on power (and wine), and used to getting what she wants....until hopefully that slap woke her up.

Okay, so I'm not as keyed in to all the ins and outs of JM's behavior on and off set but it's been difficult to ignore stories. Ones like, JM won't work with Archie and the infamous "feud." It seemed as if JM drifted so far away from her original cast mates, you never saw her in a scene with anyone.

So, is JM as cold, selfish and drunk on power as everyone suggests? If so, did she act that way from the beginning? Or has the transformation of AF truly mirrored that of her off screen persona?
