Raza and Miranda Separated/Divorcing

[age1021]

Maybe I am reading too much into it, but why did the article bring up the fact that Miranda's character in spooks spent more time with Rupert Penry Jones character?

"The couple married in September 2007, just as Mr Jaffrey left the show. Ms Raison then took a more central role alongside Rupert Penry-Jones, who played station chief Adam Carter, until his character was killed off."

odd....or maybe I am reading into it...
