Zavala scribbles it on the inside of the forearm, 卌 in crayon

I'm an exo and I have been reset a lot... but it's encoded into to me and so I remember

They have something hard coded into them. A number that increases for each reset. Supposedly something that can’t be faked. It’s not the paint job on their faces. But think of it like a file on their operating system. [quote]By default, Exos had a number appended to their names that signified the number of reboots they had experienced, with the original human used as the zero-index. Hence, to use Clovis I's example, the human John would be followed by the Exo John-1, John-2 after one reset, etc. [b]This number was stored in the Exo's memory as hardware, and so could not be forgotten[/b].[18][/quote] In Caydes case. He left a note to himself in his journals telling himself that six was the final number he wanted to be. And wanted to die if it increased again. He said his closest friends knew this, so if the person reading this is version 7 or higher then someone isn’t playing fair.
