Clara walks inside the Tardis
Clara: River what are you doing here? I thought you were dead
River: time travel sweetie. We are all alive and all dead it the same time, surely you should know that by now
12th doctor: anyhow river where were we, Amy Rory angels were did you say they are
I don't know exactly but they gave be a clue Pompeii
Doctor: better not be volcano day because then I can't help you see I already went with Donna and I can't rupture my timeline good times… I remember we thought we were in ancient Rome and then the earth quake happened and I saw Mt. Vesuvius and realized I messed up and we were in pompii but we couldn't get back to the Tardis because…..oh my Prydonius….i knew this face was familiar it was on my tip of my tongue… of course it all makes sense now… and Amy that soothsayer …how didn't I see this before….but Pompeii wasn't angels but still…..okay doctor shut up and lets go to Pompeii and see my past self…wait I am forgetting something …get it together doctor… okay so river Clara, the weeping angels are going to come after me two doctors three tardis's can't be a coincidence they are going to look for me so listen this is very important I am going to land the Tardis 20 weeks early so the weeping angels won't be suspecting our arrival yet before I change, here's a list of instructions for when I'm human. One, don't let me hurt anyone. We can't have that, but you know what humans are like. Two, don't worry about the Tardis. I'll put it on emergency power so they can't detect it. Just let it hide away. Four, No, wait a minute, three. No getting involved in big historical events. Four, you. Don't let me abandon you. And five very important 5 don't let me eat pears I hate pears, pears are the only food that every one of my mouths absolutely despised, now Caecilius is a character I will have made up but he won't know that I'll think I am him and might do something stupid like eat a pear and in 4.6 months I don't want to wake up from being human and taste that And twenty three. If anything goes wrong, if they find us, River, Clara you know what to do. Open the watch. Everything I am is kept safe in there. Now, I've put a perception filter on it so the human me won't think anything of it. To him, it's just a watch. But don't open it unless you have to. Because once it's open, then the angels will be able to find me. It's all down to you guys it's your choice. Oh, and thank you…okay let me just make up a story for Caecilius you know roman stuff, oh wait I forgot River, The Doctor you will meet hasn't meet you yet and it has to stay that way so It won't cause a paradox, so River you have to put on this clocking devise (doctor gives river cloaking devise and her appearance changes) oh and Clara would you put on something Roman -ey , I know no one cared when Donna went but in 21st century clothing but she wasn't wearing a dress with crosses on it. Really, Clara we are going to 79 AD during the Roman Empire do you want to be executed?
Clara: I had no idea you were coming I came here because I had to use the loo
Doctor: you're just full of sass aren't you Clara
(Clara exits through a hallway in the tardis)
Authors note: i don't know if you noticed but most of this chapter is a reference to when the 10th doctor used the watch to become human in human nature
