final scene

So fit my final scenes I need to have myself kill a clone of myself  and for that I need after effects,  a software I've used before, but on a trial period. I'm thinking either I come up with some really clever editing or I might need to purchase a moth of After effects. On top of that the scene Asher will either be me floating in a tank. Or me waking up again, the latter of which I already have filmed. I've also busy realized I can be the main character and cameraman so I will enlist the help of of of my friends to either play the part or record.
