> Um, just as a side observation, but didn't Jacob technically invite everyone into the dinner during his haste to get there? Meaning Lorne being there isn't too far off?

No Isacc was invited and Thalia is there because she's the princesses guard. It's a normally just family, however Isacc's a visiting Lord, so it deserves some respect. Also no one is brave enough to try and remove Marianne from Jacob.
