Just become best friends with either the Second Owner or the Overseer and hang out with them. The Overseer has the Spirit Board but the Second Owner has cereal, so it's a toss-up.

Actually, the whole time Seyrun plan was to pay a visit to the Second Owner, she'll just verify the status of the ley line near the Tohsaka residence and then take a trip to the Einzbern castle, after all, it's the tradition of civilized Magi to pay a visit to the owner of the land before truly setting in.

Also, cereal, how can one pass on it?

Seyrun is just making she she doesn't get killed before she can do anything. Mainly because she fears Caster. BTW, should Berserker be able to feel her Magic Circuits being turned of even though Berserker doesn't know anything about Magecraft?
