Disclaimer: I don't own Voltron Legendary Defender
Author Note: This is pre-canon, where the Blades are raising Keith and Pidge at headquarters, and the two are best friends with Regris, who is just a bit older than Keith. In this AU, Keith is five, and Pidge is two. This is also Thulaz.
The Blades, specifically the five highest ranking ones, were wrapped around the tiny fingers of their three kits. It was natural for Krolia to be partial to Keith and Pidge, but when the pack brought Regris into their pack, Krolia adopted him as one of her kits as well.
Keith's fifth birthday was approaching, and Krolia took him on a trip to Earth. The duo had returned with a small wolf pup in tow. It turned out to be a cosmic wolf pup that had bonded with Keith, and now, the two were inseparable. Wherever Keith was, the wolf was too, even in the nest.
Kolivan, Antok, Thace, and Ulaz truly didn't mind the inclusion of the wolf into their pack. He was a member of their pack as much as Keith, Regris, and Pidge were. Speaking of the baby, she was two and completely curious about everything, including the wolf pup, who grew quickly and was soon big enough for all three kits to nap against him at the same time.
The wolf was given the name Cosmo and had wormed his way into everyone's hearts. Keith had taken to even riding him in the smaller training hall. However, what warmed everyone's hearts was his interactions with the smallest kit. Thace and Ulaz were initially worried about their baby, but both kit and wolf showed them they had nothing to worry about. Cosmo was extremely gentle with Pidge, no matter what the kit did.
It was even cute when the kits and wolf played with each other. It was during one of these times, when Thace was watching them, that they discovered that the wolf could teleport, which surprised him. Thace had panicked over losing Krolia's beloved kits and didn't want to be the one to tell her. He made calls to the other members of the pack (minus Krolia) to see if they knew where Keith and Pidge (and Cosmo) were. Fortunately, Kolivan told him that the three were safe. Kolivan had been startled when Keith, Pidge, and the wolf had appeared in his office, ending up in the nest he kept in his office for his pack members.
It was even more shocking when Krolia encouraged Cosmo to turn it into a game. She would actually tell the wolf to teleport Keith, Regris, and/or Pidge somewhere, and she would seek them out. Of course, there were places that were off limits like the hangar and any ships that were there, but that still left a large section of headquarters to search, which was the reason why mother and kits (and wolf) were napping in the familial nest before the evening meal.
However, when Ulaz and Thace checked in on the group, they could not see their baby. They started to panic before they saw something adorable. Pidge was curled up on top of Cosmo, nestled in the blue fur, asleep.
