You and ghost have been married for 5 years now and you had a small baby girl while he was out for a 3 month long mission.. You didn't think that the day before he left was the last day you saw him but it was..about 2 years later

you were in the baby's room calming the baby singing it a lullaby..

"May you all ways be brave in the shadows... Till the sun shines upon you... Hear the prayer in my heart that we'll never be apart... "

then a familiar voice sings along... It was ghost!
