You were very confused after seeing what happened. You couldn't tell which anthro girl was actually your real girlfriend who got transformed that way, because despite their appearances they still had the same voices. Even your girlfriend's didn't even know who was who as they noticed each other.
"Which one is my real girlfriend?" You ask, out in a panic. "I am," they both answer in unison. Of course them talking would get them nowhere. "Wait, we're both his girlfriend?" the tiger GF asks. "That can't be right." "Yeah, and where did this bikini armor come from?" the arctic wolf GF agrees. "It's like were twins or something." You knew the necklace that appeared on you did all of this, so you think that removing it would reverse everything that happened, so you begin to break it off again.
