You hold still for a moment to make sure that Rebecca did not spot you. Once you are sure you are safe, you think about your plan of action.
"If I transform her, then those two guys with her could probably overpower me really fast, not to mention she has at least 3 maids and who knows what else. I have to find some way to get that book away from her" you think to yourself
You come up with an idea - give yourself the power to transform yourself into something that she will not notice, and steal the book back.
You think for a second, before settling on a frog. You had considered a fly for a second, but thought against it seeing that you would be extremely defenseless.
You pull out your TF-Note, and write that you have the power to become a frog and return to human again.
With your disguise set, you transform into a small classic green frog.
Your TF-Note falls on the ground, you slip it under the sofa you are hiding behind. You think that will keep the TF-Note safe.
Hopping out from your cover, you dart into the foliage surrounding the backyard. Looking out you take note of your surroundings.
You see many other animals across the backyard, but as for people that you need to worry about, you only see Rebecca and the 2 men next to her. Fortunately, she seems to be occupied with them at the moment. And just behind them, you spot her TF-Note! Completely ignored. What luck for you.
Working your way around the perimeter, trying to make as little noise as possible, just in case, you eventually make it just behind them. Watching the guys next to her, one of them starts kissing her ear, blocking out any noise. This is your chance! You stick out your tongue and grab her TF-Note. The rustle just sounded like leaves in the wind, and she didn't even bat an eye. What luck!
Slowly making your way back to your sofa, you regain your human composure, still hidden. You open up Rebecca's TF-Note, and find tons of transformations. The sofa that you are hiding behind your ex! "Well suits her" you think. But now you need to deal with Rebecca.
