Bakugan Battle Brawlers #11 ~ "Grandpa's Got A Brand New Bakugan" 
  
Episode starts out with Dan battling one of Masquerade's minions. He wins but then passes out. When Dan wakes up, Marucho proposes that they need all 6 attributes. He then says they should get Shun, No. 1 bakugan player in the world, on their team, because he has Ventus Bakugan. Runo agrees but Dan is against it. However, Runo and Marucho go to see Shun anyway. They enter his home, only to run into traps and eventually Shun's ex-ninja grandfather. Shun's grandfather attempts to attack them but Runo and Marucho accidentally pull out their Battle Cards and stop time. They walk past him and restart time making him fall into his own trap. Runo and Marucho then hear Shun playing on his Leaf Whistle and find him.

Bakugan Battle Brawlers #12 ~ "Bakugan Stall"  
   
Alice is working in Runo's Family's Restaurant, and all of the guys seem to have a thing for her. Alice is worried about telling Runo about her grandfather being Hal-G, the human who corrupted Naga's mind. Runo is still troubled about losing to Shun, and breaks a cup when Alice comes in, making Alice unable to tell her about her grandfather. Skyress asks Shun if he is all right, to which he responds, "I don't know". Dan is looking up his ranking, now at 97, and is shocked to see that Runo is nearby as well. He then sees that Shun is in 6th place, and shows that he is unsatisfied. Drago asks about Shun, and Dan tells him that he was at the Top, but then stopped playing Bakugan. Dan then tells Drago how he and Shun used to be best friends when they were young. He says that he and Shun were the ones who started the game of Bakugan, and that Shun started to come onto the chat site less and less.
