The witch was very much a fan of letting people cope in their own time. To a certain degree, but Elena was a different matter altogether. While she knew Elena, she didn't know Marguerite, so she wasn't even going to try and press issues until the other woman gave her voiced words to do so. So she didn't mind the periods of silence as Marguerite digested information and came to terms with it, as much as she could, anyway, in her own way. Elphaba did enjoy silence, though experiencing silence was strange to her again now that Galinda was gone. Elena wasn't exactly silent herself, but she wasn't as bouncy as Galinda was, so the silence was certainly more noticeable, and in many ways, more empty now.
As much as Elphaba was trying her best to not brood, she knew she was. She was rather a different person without the bubbly blonde witch there. Elphaba was far more reserved, far more introverted than usual. If she didn't have Elena, the green-skinned witch would undoubtedly have begun reverting back to how she'd been before her arrival at Shiz University. But as she did have Elena, she was just far quieter, keeping her nose stuck in a book more often than not. Even with that, she still managed to have found two new arrivals recently and helped them out. Which only spoke to the progress she'd made in her people skills since being here in Lawrence.
"Well, not one we can control. Just as you can be suddenly brought here, you can also be returned back to where you came from without warning. No one really knows or understands why or how this is." She wasn't sure whether that would give Marguerite hope or not, but it was a fact of the Seal she needed to be aware of. "And it can bring anyone from any time and any place." Which was also another fact she needed to know in case someone she knew was here all ready or if someone from her world were to show up here in future.
When Marguerite said Oz in a questioning manner, Elphaba was inwardly relieved. After all, anyone that wasn't from Oz and knew of it most likely knew The Wizard of Oz and that would've put a bad start on this. After all, it was one thing to be called a wicked witch in her own world for standing up for an injustice. It was quite another to be called a wicked witch in another world when you were wicked simply for the sake of being wicked.
"It is a land completely different from this one. I was born in a place called Munchkinland. It is a place where magic exists." She looked at Marguerite a bit carefully. She well knew from her reading in this world that witches weren't always thought of favorably, so she was going to bridge this topic as gently as possible. And, you know, the fact she sort of had green skin.
