July 31st
I had hoped it wouldn't take this long for the plan to come together, but it isn't easy planning a jailbreak with three misfits against fifty guards, workers and doctors. Sombra was all for it, but Chrysi was a little hesitant. Because changelings are so discouraged in Equestria, she never truly learned how to shape-shift.
She has spent the last month practicing morphing into me. The first time, she mixed up the sides my wings were on and my eyes were the wrong color, but she has slowly gotten better. She had me down-pat, and soon after she began practicing a guard we had been seeing a lot lately. He works the day shift, and we've done our best to memorize his looks when he passes by.
Tomorrow is the day we'll break out. We'll all get up early, waiting for when that poor guard will walk by.
Sombra will do the rest.
You see, he hasn't been 'clipped' this week.
