I had some sweep of what I wrote for Doc and most of them have him being the reliable one. But! I did manage to find some :)

- Doc being traumatised and Thatcher comforting him in the end (Doc/Thatcher)

- Doc pushing himself until he’s extremely tired, so Jackal tries to help him (Doc/Jackal)

- Doc in an alternate universe (Dead by Daylight) where he suffers a doctor’s nightmare. This is more on suffering and he sees other people to give him comfort, but I think this was the cruelest I’ve done unto him.

- Doc berating himself and Lion comforting him (Doc/Lion)

- Doc couldn’t save a recruit. I wondered if this should be added here, but hey. Suffering is the half of what you are craving so I hope it works ;_;

-

I also asked some of my friends about their suffering!Doc.

- Doc with friends’ OCs. He is being comforted by @acidartworkonly‘s Acid, and @ask-team-rainbow‘s Soutien. The fic is written by @r6shippingdelivery.

- Doc just suffering. Major character death. (Doc/Montagne) This fic is written by @r6scaliber.

Iana is an essence of a moonlight, hence she is really pale. The very being of moonlight materialised into a humanoid form. But she can't get back to the moon, back to the space so she always yearns to be back to her home. So one of her ability is to make a clone by manipulating light wave. 

Alibi is a shimmering mirage from Lybian desert. Mirage, the trick that plays on people's eyes, but she is as real as illusion can get. A personification of what people hallucinate while feeling dehydrated and fatigued. That's when she gets them. Lure them into deeper part of desert. Leading them to death while wanting what they can't grasp.

People think they don’t interact much with each other because Iana seem to be appearing only at night and Alibi during the day.

BUT

Sunlight exists day AND night. Moon isn't a celestial body that produces light itself - moonlight is just reflection from sunlight.
