You're Lucifer's sister, Charlie's aunt. You were still in Heaven, but you would occasionally use your magic to contact Lucifer, and you already knew he had a daughter named Charlotte. You've both heard about each other from Lucifer, you both just haven't met yet.

And now, Charlie really wanted to talk to Heaven, so Lucifer, being the dad he is, contacted you since you could ask the higher angels since you were one of the higher angels, meaning you were higher than Adam himself.

After you got the message, you decided to take a trip to Hell to visit your niece, your brother, and her hotel. (Btw, Niffty double cleaned the hotel)
