That sounds heartbreaking noooo. ;( DON'T WORRY BULL Lav is here to protect all of you.
Fine by me! Honestly, I don't really plan on canon-bumping him into any of the DLCs, so you can go wild with it. Lavellan will want everything laid out for him because he's Like That. Also pls drop the news about Solas so he can brood intensely for a month~
