Marrow

It's always been the two of them. Marrow knew for a long time he'd bring his Mudskip with him when he eventually left his parents to start his own family. Mudskip was family in a way they'd never be able to comprehend. 

Expanding was interesting. Mara never showed it but Marrow knew she was happy to have a new home, and new puppies to look after. Calliope and Freya were excited to explore and Marrow loved them for it. Snowdrop was scared half to death in the beginning but had grown into such a fine medic. His sweet bondmate was overjoyed to have constantly have puppies to babble to. Marrow was horrible partial to outcasts. 

There were a few bad eggs. Shard, who came in spitting and left with most that day's hunt. Davina, in all her quiet meekness, Marrow never expected her to go after another wolf, much less brooding, cutthroat Mara. It's painful sometimes, but he takes good care of his family.
