You possess the nun.

To make it more entertaining you don't possess her by having your host touch her and slipping in, instead you leave your host and make yourself visible to your new host while appearing like a Japanese priestess you once possessed. When you're sure she sees you, you look at her pleadingly and ask for help. ''Help?! Help me? please, can anyone hear me?'' The young nun is too surprised and maybe too afraid to react to you so you look defeated and float away.

As expected she follows you. When you think you found a place where you can be alone with her for a little while (the toilet was the only place for that on the damn plane) you interact with her again. When she finds you crying on the toilet she looks concerned but doesn't know what to do, it's likely that you're the first ghost she sees. Not surprising as even you have only met a handful of other spirits in your many years of being one. As she stammers you look up into her eyes, grab onto her shoulders and bury your face into her neck. ''Thank you,thank you, thank you.'' you continually whisper as you cry into her neck while grinning like a Cheshire cat. Then you move into her and continue your whisper inside her head.

''Did-dis she just possess me?!''

_''I'm sorry. I couldn't resist. Without a host I need to steal life **** to survive.'' _All of it is true, but none of it connected to each other.
