Am i the only one who thinks Olver might be a darkfriend?

 

Something which would open a super creepy closet full of possibilities regarding Olver's story of Darkfriends killing his parents.

Olver's PoV in ToM Epilogue doesn't really read like a Darkfriend:

 

Olver was Mat's personal messenger, all official and everything. It was no wonder Mat sometimes forgot things, but it was Olver's job to take care of him. Now that Lopin was gone, Mat would need extra taking care of. It was one of the reasons Olver stayed with the Band. He was not sure what Mat wold do without him.
