If I end up getting the pack my general idea is to have the Grim I play as a separate character be able to actually go back to work as a Soul Reaper, without me having to mod the game. I'd also like to see at least one of his children follow in his footsteps, and probably give his wife the Undertaker career. I'm thinking this could be the start of a real family affair business, but of course none of this is going to happen if the game either doesn't allow relationships with Grim, or if it interferes with current cheats and mods that do allow you to build a family with him.
