Debating whether or not I want Tyrael to make an appearance for Mar and Lyn, but I'm thinking of keeping him out of sight for future appearances.

Also I believe that Darius is in or at least near the Infirmary, if you wish to interact with him. Presumably Athalus is there too, but Rtron has been gone for a while so I don't think it'll be a good idea to expect a responds from him.
