You decide to spend the day training Ari personally.
You start off with something basic: giving everyone except Ari a paintball gun, and giving her a foam padded boffer-sword.
"Uh... not to criticize your training technique bro, but what exactly is this supposed to improve?"
"Lots of things. First off, situational awareness: You need to be aware of us as we sneak up to shoot you, and from unconventional angles. Secondly, reflexes: You're in good shape physically, and paint-balls like these are actually rather low velocity projectiles. It's not impossible for you to use the sword to bat them out of the air, or dodge them without getting any paint on you given the cover rich environment that is this half of the hangar. Thirdly: Paint-balls hurt, and leave an immediately obvious mark when you get hit. It's motivation to improve, as well as a handy index of exactly what your shortcomings are. Now, rules are simple: We either go until you give up, or you've managed to hit ALL ten of us with that sword."
After about an hour, she managed to both complete her transformation into a horrible rainbow monster, and take out the last of the shooters. When she got out of the shower, you went straight into a Simulator session. Keeping with the them of avoiding getting hurt, you stick her in a high mobility suit without weapons and see how long she can play hide and seek against your team. The answer for the first six rounds were as follows: 26 seconds. 54 seconds. 2 minutes 30 seconds. two minutes 50. 11 seconds (Jumped above the buildings, right into Elsie's crosshairs). 5 minutes and 32 seconds was the final round, right as she really started to hit her grove. So you immediately changed tactics to throw her off balance.
