Knowing that Dr Small needed to test out the ray gun on either Zack, Cody, or both, they all decided to head to the twins' bedroom, just to be absolutely safe from anybody watching. Thankfully, the boys' mother, Carey is out for a long while, leaving just the two of them on their own.
On the 23rd floor of The Tipton Hotel, the boys actually lived in a four room suite, which one consists of the combo of living room/kitchen area, the other is the bathroom, while there are two bedrooms in the suite. One for Carey, and the other for the twins they shared a room with, and so they decided to test the ray gun in their bedroom.
Of course when it comes to two beds, there was a stark contrast between the two, when Dr Smith first went in. On one side is somewhat messy and stuffed being life either on the floor or on the bed, while the other side had the tidiest out of the two, so he decided to place the case on Cody's bed and takes the ray gun out to try it out. All the while, the twins can only look on, and it seems as though Cody is a bit concerned more than Zack, which he questioned his older twin about an idea being a subject to The Doctor's experiment.
"Umm...Zack? Are you sure having The Doctor in our room is such a good idea?" Cody wondered in concern.
"Oh, it's fine! Besides, what else could go wrong?" Zack just simply brushed off with a smile, not knowing this thing can make anything or someone smaller rapidly.
As soon as he was ready to test it out, The Doctor stares at Zack and Cody, and curiously asked when setting up the dial for the ray gun.
"So now that we're ready to test this thing, who will be so brave to get tested on?" Dr Small wondered with a wide smile.
The question, which of these is about to get shrunk down to size?
