Okay, so what does Forcegreet actually do? I assumed it made the NPC walk up and initiate a dialogue tree, but it seems like they just say out loud whatever is at the beginning of the tree without actually making the player "engage" in the dialogue. If that's true, how do they make characters like that one lady at the Thalmor Embassy party walk up and talk to you? Elenwen i think her name is...

Hmph.

Nvm. Figured it out, if there is not connecting topic, they just say it out loud.
