I thought we saw a clip of the handwriting somewhere. Looks like a young woman's handwriting.Two things have stuck out to me recently with Catherine.
1. They did a segment about Sean and Catherine in Sean Tells All, I think. And there was something in there about all of the notes Catherine has sent him. I think we saw the kiss one during the season, but apparently she has given him lots of notes.
2. When Des took Sean aside before she was sent home, Catherine had a confessional where she stated that maybe she should have done the same.
I think it's simply a note/letter from Catherine to him "before" her final meeting with him.
I haven't seen last night's episode yet, so I don't know if there is anything there that would make me change my mind.
