Ivy here.

I really started to miss wearing jeans after walking around in Asgardian clothes for a while. They were beautiful clothes, but the long skirts were more than a bit of a tripping hazard for someone who wasn't used to them.

I followed along behind Thor and Dr. Foster. They talked in voices too soft for me to hear them. They paused for a moment next to a railing, still talking.

Dr. Foster and I attracted plenty of curious looks, but no one approached us.

"My father does not know everything," said Thor.

"Do not let him hear you say that," said a voice behind us.

I turned to see Thor's mother.

At that moment, something twisted in my stomach and I wanted to throw up. I didn't know what to do. I thought I'd come to terms with what I'd decided. But until now, I'd never had to face it like this. I tried to open my mouth, to say something, but my tongue felt refused to move. My heart thudded against my ribcage and I felt sick.

"Mother," said Thor. "Jane, Ivy, this is my mother."

"Hi," said Jane.

"Hello," I pushed out.

I've never been very good at hiding my emotions or thoughts. But at that moment my body was on autopilot, doing the normal things it would upon meeting someone – smiling, saying something about it being a pleasure to meet her. She didn't seem to be picking up on anything strange in my behavior.

If Thor's dad didn't kill me, then either he or Loki would. But what was I supposed to do? I'd prayed over my non-interference rule. I'd thought I was doing what was right. But letting someone die would be nearly the same as putting the knife in them myself. Wouldn't it? But if she didn't die…

A horn sounded. The attack. Because it would impossible to cut me some slack, even for a minute.

"Go. I'll look after them," said Frigga.

He left.

She led us in the direction he had headed.

"What's happening?" asked Dr. Foster.

"An attack."

I followed them through the streets back to the palace. To say I did a lot of thinking on the way to there would be a hilarious understatement. I believe I've laid out my dilemma already. Now, find me an answer, would you?

Commitments are so easy to make – not always so easy to keep.

I'd considered warning her, talking to her about it, then had discarded the idea. Imagine how to bring up that subject. On one hand, she might consent to hide until it was over. On the other hand, it could mess up the timeline later, since Loki would be alive afterward, pretending to be her husband.

We entered the palace, meeting Thor and his father in a hallway.

"Stay with them," Odin ordered Frigga.

"Be careful."

"After 5000 years of survival through war, my wife still worries about me."

"It's only because I still worry about you that you have survived 5000 years," she replied.

Their exchange was only a few sentences. But, somehow, it made what I would have to do much harder.

The two men left.

"Listen to me now. I need you to do everything I ask – no questions," said Frigga.
