Imoen's Gorion dialogue: give closure for all dialogue paths

[Gitjas]

Some of the answers you can give to imoen after you check gorion's body, do not lead to you actually bury him. But.. this way it doesn't provide closure. A chance should be given anyway to the player, no matter what dialogues choice you've given.

There is another way of closure, The Candlekeep guard who protects the main path and demands for the tome for entry can arrange for Gorion to be buried in Candlekeep.
