Azula was laughing in her head. She was getting Ruby on her side. She then whispered "I think we need to ask him questions Ruby."
The Doctor heard whispering and said "What was that?"
Axula said "Nothing Doctor."
The Doctor nods and pulled everyone to the center of the TARDIS. "Ruby hold this Lever. Azula you control fire right? then heat this up. Maria can you try and get power to this thing use your magic if you have to." 
Azuka said "What are you doing?"
"Im going to help them." He got out the Sonic Screwdriver and saw the battle going on. 

Doom managed to block Kuwabara's strike but was knocked back by Dianors. He then saw the Doctor. "Three against one...I havent seen something like this...only took ok four." 
Doctor said "Doom.....stop...I can help you get back to your world. I can help everyone get back to there world.:"
