Some stuff from the "Ingo in the DSMP AU" (Part one):
When Ingo fell from the sky, there was a mess in the communicators of everyone. It wasn't programmed to receive new people in the DSMP considering the arrest of Dream.
Ingo as well as I said in other posts, fell on waters aside of Snowchester. Tubbo and Ranboo were the ones who get him safe, it was confusing and they suspected a little about him, but Ranboo was the one to suggest bringing him to the mansion, at least until he woke up and they could interrogate the man. Tubbo didn't like the idea, but after putting Michael in a safer place, he felt more comfortable with the plan.
Between the lapse of Ingo being helped and when he wakes up, Tubbo and Ranboo had the opportunity to meet Ingo's Gliscor. It happened when they left the man to rest. After a while, Tubbo checked the restroom just to see the immense bat-like creature over Ingo, curled on his body. Tubbo had to retain himself from attacking the thing. After all, it seemed to be guarding the man's sleeping.
Ingo and Ranboo talk to each other every time they can. After all, both have memory problems, maybe they can figure out a solution.
Ranboo teaches the man how to fight. The idea came when both husbands hear how different was the world from where Ingo came from. And they started to do it after seeing the panic in Ingo's eyes, and his little knowledge with fighting monsters in the night.
Little things on the man like his voice, his ways to talk with train terminology, and his poses helped a lot to make him less intimidating in Tubbo's eyes. "He's a little dorky, I like it!"
Ingo is considered Michael's warden in some way. Or well, that's what Ranboo thinks when the amnesiac man talks to them about the wardens and pearl and diamond clan.
They give the man the work of protecting Snowchester and their son while they aren't on there. Ingo accepted it almost instantly.
The first construction project of Ingo was a subterranean red of mine carts, it isn't complete for the moment. He just mined the space he needed and only goes to L'manhole.
Talking about it. One night, they got to the big hole that a lot of time ago was L'manburg. Tubbo talked about his history, and between tears, he sang the anthem. Ingo followed him with his flute.
Sometimes Ingo gets homesick, not only from the place he doesn't remember, Hisui starts being the cause of some of those sensations too. When he gets like that, he comes to Michael's room to interact with the young one.
Sometimes he carries him running on the mansion and making train noises. (Even if he doesn't know what they are)
Ingo feels grateful for the couple of platonic husbands. Only the almighty Sinnoh would know where he could be if they didn't help him. That's kinda the reason why he tries to help all he can with his Pokemon.
In the fall, Ingo lost his bag of things. It was a big luck that he didn't lose his pokeballs and Celestica Flute.
The first thing Ingo crafted was a shield. He called it "Fero" and the second thing was a Diamond sword with the ones Ranboo gave him. He called it "Caril". Ingo usually says they shouldn't be separated...
Feel free to ask and maybe put more!
