River watched from a distance, deciding not to interfere until it was absolutely necessary. She saw Alexander create the ice chains to hold the yeti before Briar started plummeting towards it. It was then that River realized there were still people underneath the yeti, she had seen Liliana come out but as far as she knew Connor was still underneath the yeti. She quickly directed her eagle to fly underneath the yeti, she spotted Connor and pulled him up onto the eagle and managed to make it out just before Briar's attack hit.
