Do you mean during your little boy scout meetings? It's unlikely that they can do much with that other than mine you for information, and you already provided tons of that. If you mean they can pull something off with all of you together in a single place, that depends on the site. Away from the ruins, I doubt they can do much either. There are a lot of conditions and circumstances to the bigger spells. Oh, they know how to open the gate, but I'm unsure how. Perhaps it's one of their memories from before our time at school. Maybe they came upon a particular item? They aren't exactly forthcoming.
