Puffadder is the newest member of the pack being taken in from another pack that had passed by with her heat. Easy to say that Redzenious quickly had her join his pack and start their way toward making an heir. She didn't seem to mind as she sneakily made her way from her old pack though Redzenious was willing to fight.
With a sneaky loner personality, it makes only perfect sense that she'll be the perfect scout. Always on edge and untrusting of others than her King who won her over easily with his aggressive display. She's never had a problem being on her own even exclusive in her old pack as well as her new.
Disappointed that she did not bare him an heir Redzenious (that is what they are saying, he had run off the pups at a young age) moved on settling her into a hunting party of just her own so she wouldn't throw off the synergy of the other party but with this, she is working hard to prove herself as a hunter. Most of her hunts she comes back with her prey. But as soon as Redzenious stole Copperspark she had an instant connection and adopted her, almost sharing the pup with Ceadertooth.
With the arrival of her cousin, her insecurities about her 'lost' puppies eased a bit, and with the other's pregnant and Redzenious on a kidnapping spree, she was about to be surrounded by puppies. But even being surrounded by all that little life she felt empty for losing her first litter, even when her next heat came around and she had her litter there was still a hole from her missing pups. So she continues to help Redzenious in stealing puppies and doing shaded forest puppy buys.
