Any Ideas?

So I've been thinking about this for a few days now and I'm still a bit at a loss.

1st time Rook meets the Inquisitor, it's when the Inquisitor is in possession of one of the Wolf statues that holds the key to Solas's regrets. Im on my 2nd playthrough and have only done romanced Lavellans so I don't know the difference in dialogue if you do otherwise, but a romanced Lavellan gives the statue and has dialogue that makes it seem like the statue would provide more context as to what they were as a pair.

However literally none of the regrets have anything to do with the Inquisitor or the Inquisition as a whole. So my question is, why would the Inquisitor have the statue in the first place? My only theory would be Solas's way of giving Inky more knowledge of his past, as I'm sure he'd know Inky would meet Rook at some point. But Inky themselves don't even see the regrets so that theory wouldn't even work. I just don't understand the point of them having it other than to move the story along to get them to meet in person
