Beatrice came from a pack with many wolves. The high amount caused wolves to be separated into certain groups. When born into these groups there was no chance of getting out. Beatrice was born to be a pupsitter. In a normal pack this was important as any other role, but in her pack it was considered the lowest rank.
Wanting to make something of her self instead of staying in a pack where she knew she'd never achieve anything she left. She was sure to say goodbye to her parents first, and the two wished her luck, knowing she deserved more than what the pack had to offer.
Beatrice let the winds guide her, and she came across a wolf named Tala. Beatrice could sense the strength of the she-wolf and knew that's what she wanted to that strong one day. Tala showed her around the new lands and told her of a newly formed pack of only males, Tala offered to introduce them and Beatrice agreed.
When she met the wolves she was immediately smitten with Dante, but became disheartened when she learned Dante and Vergil were mates. She was sure to keep a friendly but distant disposition, liking the two and wanting to be a part of the pack.
When Dante came to her about the possibility of a poly relationship she didn't hesitate to get confirmation from Vergil. To agree without hearing it from both wolves was something that went against her morals, as her parents raised her to have respect and to never assume.
When she talked to Vergil and was made aware about how it made him uncomfortable she was going to turn Dante down. But Vergil insisted that everything would be fine and he wouldn't stop Dante from being himself. Knowing she wouldn't change Vergil's mind she instead told him that she would earn his affection as well. She knew Vergil didn't believe her but every day she tried her best, making sure to spend equal amounts of time with both wolves.
When Vergil approached her asking if she'd want to be mates with him she was thrilled and happily agreed. Vergil let her know he wasn't interested in mating and she promised to respect his boundaries.
When Beatrice became pregnant with Dante's pups she was happy to be having his first litter. She was surprised when Vergil seemed more eager about the idea of pups than Dante and throughout the pregnancy Vergil attended to her every need, sometimes even shooing Dante away. Beatrice was amused at Vergil's behaviour, sometimes joking about how he was acting like he was the one pregnant, as he was fussier than her.
