Hmmm. Now I'm wondering whether marrying
Muiri would be a good idea or not.
Turns out you can marry her only if you join the DB, and eliminate both of her targets. Afterwards she is immediately grateful to the point of willing to marry you.
Now, on the one hand, shes an assistant Alchemist, so she'd have a great partnership as your wife, poisons and the like. Not to mention the fact that she knows what you do for a living, so no lame excuses as to why you're leaving so suddenly in the middle of the night, or where the blood came from.
On the other hand, you get her mad in the slightest and you're asking why one of your guildmates is outside stalking the house...
