MONA already expected it but she was still quite taken aback when she found out that Nikolai destroyed a good portion of the Spencer Castle. To be precise, he destroyed the part of the castle that belonged to Russell Spencer. She didn't need to ask why the emperor did that.
[Either Gavin or Lady Audley told Nikolai how Young Master Russell had treated me.]
But to be honest, she didn't care about that anymore.
"It's gone," Mona whispered to herself. "The tree is gone…"
She couldn't ask Gavin Quinzel what happened when she was taken to another dimension because the commander was still unconscious.
Moreover, she couldn't reach her Spirit Guardians as well.
[I'm worried.]
