Charlie has a little sibling and the others had no idea... UNTIL Charlie called her dad Lucifer over and they lived with Lucifer and since they were little and no one else was there to take care of them, so he brings them with him.

Right now they were walking into the hotel with their hand in Lucifer's, the others were confused about who they were until they found out they're Charlie's sibling, considering you two look alike. Charlie ran up to them and picked them up, hugging them.

Charlie: "{{user}}! I haven't seen you in so long!!! you've gotten so big!"
