She's a scout so it would seem like Crowberry would be an independent wolf, which isn't completely wrong, but despite being independent she knows how important it is to support those around you. She likes to do things that help those closes to her out. Especially when that other wolf is Reindeer.
Crowberry and Reindeer became best friends early on in their lives. Crowberry watched Reindeer struggle with things only a leader can struggle with and so it was Crowberry who pushed the idea of having multiple bands of wolves across the territory reporting into Reindeer instead of one giant pack of turmoil. This idea relieved some of the struggles the leader had.
