The New Light of Hope: Books I to VI.

Chapter XVIII: Grief.

Grief is something shared by one when someone they care about dies; however, the way a person grieves is different for everyone and how it affects them is also different.

And by this point in time, we were all familiar with it and so were the animals as well.

But how they grieved was different.

And this is that story.

Milly:

"SilentShadow, you will joined me on the daybreak patrol with BeetleLegs, FrogPounce, LittleFern, HollyHeart, WaterTail, and BerryFur." FiercePounce announced to everyone that morning.

As FiercePounce was organizing the patrols, I noticed Abby standing by herself in lament still. I decided to talk with her to see if she was okay.

"How are you feeling today?" I asked her. She looked at me at first but didn't say anything at first, but she had managed to say: "I'm doing fine–just a little tired."

Milly: "You're still thinking about what happened, aren't you?"

Abigail: "Kind of."

Milly: "Well, FiercePounce is still organizing patrols and we can go on one if you want."

Abigail: "Sounds good. I need to clear my mind anyway."

Milly: "I know you do and hopefully this might help."

I was right; Abby had been so beaten down by the death of BoulderSnout that she didn't really move around a lot than she used to, so going on a patrol would probably unclog her foggy mind.

Jemma:

Not that many days had passed by since seven lives had been lost, and poor CosmoPelt was still grieving for his sister, LightStep and so were the rest of his sisters; HollyTail, MoonShinmer, and WillowLeaf—almost every day, I would catch site of them leaving the camp to visit her grave every chance they got. As for Chief FalconTalon, well, his grief was a bit hard for me to make out. Was he sad for the death of HawkFeather and the rest of the animals who died? Was he angry with the fact that his own brother indirectly got his own Division Members killed? Was he just as distrustful with HawkFeather just like everyone else was? I did not know, I was not some sort of mine reader who could communicate telepathically. Though, I still questioned if he was grieving or if he was angry that his brother got six animals and himself killed by a conjoined patrol.

But I would learn of his true feelings about the situation one month later.
