Why didn't they stay in the "Sorcerer"'s dimension?
- They not only found a Quinn double in that dimension, but one who had relatively mastered sliding technology. The big hurry to catch the slide window was a huge Idiot Ball, as they could have simply replaced their timer with the Quinn double's help, something they ended up forced to do next season anyway. Rather then jumping headlong into a scenario where they had 53 seconds to decide if they reached home or not, they could have used a new timer where they chose their own slide window, as the timer originally could do in the pilot, or hell, they could just try to fix their original timer. With the help of the Quinn double, who was able to select a destination relatively accurately, they could have just slid back and forth from that dimension until they got home.
