Tendo had begun looking over the generator but really didn't know what was going on with it. In the end, after giving up fairly quickly and Android 16 moving him so he could begin, Tendo looked to the sky and saw the moon there was a slight tingle of power and then it was gone. 
[i] Thats my Saiyan Biology kicking in. But since I don't have a tail... [/i] He thought as he looked around at the others. Noticing Shin seemingly frozen and listening to Waeffle speak. [i] Whats going on with Shin? [/i] he mused watching intently at the way even without being able to see power levels or sense them Tendo could tell something was coming and it got his Saiyan blood firing on all cylinders at the thought of a challenge. That was when he noticed the tail. Shinji's tail. And the world seemed to fall away all that was left were the people he grew up with and the full moon above.
