Sadly Puppe likely won’t ever be paired in a social group again. Her reproductive days are long behind her, and considering her only offspring still living with her is now a flanged mature male, I would say the chances of her being reintroduced with him are slight at best. She’s also very old at this point, and introducing her to feisty younger orangutans could potentially go not so well for her. Not to say it’s impossible, hypothetically she could potentially be introduced to Sekali and Budi again, especially once they have the space of the outdoor exhibit and Budi being a mature male, could act as a mediator between the two, but I think the chances of that are very low.
