You can also pass Jarrod's date check with 50 Poise too if I'm not mistaken.
You sure? I've seen 50 Courage or 50 Poise on the 7KPP wikia (when I looked a few weeks ago at least.) I'll go and test it because obviously, as the Princess I don't have the required manipulation or courage and I just looked at my princess save (my first ng+) and in character creation I didn't give her the (alleged) required poise either.
Will report back!! EDIT: Yeah, 50 Poise doesn't do it, sorry friend.
