The only way to beat the giant Beta is via direct attack to the brain, forcing Ogre into a very perilous situation. Auctioneer risks his life to locate the brain, and Ogre uses Number 11 to take it out and defeat Beta.

He reunites with the Squad and celebrates, but his joy would be short-lived.
You might be fine with that, 
but it'll hurt me!
!قد لا تمانع، لكنّي سأعاني
Dir mag es nichts ausmachen,
aber mir setzt das zu!
Aunque tú pienses así, a mí me duele.
Aunque tú pienses así, a mí me duele.
Ça te va peut-être,
mais moi, ça me fait mal !
A te può star bene,
Pode estar tudo bem para você,
mas é doloroso para mim!
Может, тебя это устраивает,
а мне больно!
