"There are a lot of things we don't understand about you Emma," he began in a more serious tone, his eyes also silently begging me not to be angry or upset. "We can't just up and tell you about it without any explanation, we needed an explanation for everything"

His eyes were saddened. "I was at fault for that and I'm stupid, it's just the timing was too good to turn after from, we have a reason to believe someone might have done it"

"Someone?"

"We're still looking into it"

I exhaled sharply, it was shaky and got my nerves unsettled.

"Emma"

I shifted my gaze back to him. "You used blood magic"

I narrowed my eyes.

"That day,"

"T-That was blood magic?"

He nods. " And that spell has never been seen for centuries, I'm not even sure there is a Grimoire for it"
