In Pokemon GO's Holiday Part 1 branching research, trainers face a crucial decision: assist Spark or Sierra. While Niantic's official announcement omits this free research, it runs from December 17th to December 22nd, 9:59 AM local time. This three-part research culminates in a choice between these two paths.
