The Master, because he was a total childish brat, purposefully pulled the banana flavoured ice cream over with the intent to eat it all. Even if he despised the taste of banana. Because if he was stuck here, miserable and bored, so would the Doctor be. And hopefully the freak too. Though he less wanted to bore Jack and more scare him. Or anger him. Honestly, he'd settle for endless unsettled annoyance.

With a bitter laugh, the Master smirked at Jack, unable to help himself. Well, he was right on the money. Look at what a life time of the Doctor's love and rejection did to a man. Well, that and the fact that he was just very happy when he hurt people. So many reasons why but why bore everyone with them? The Master had no intention of changing.

"Trying to be nice? What's nice about this? Imprisoned when I should be dead, locked alone all day with the drums tearing my mind apart and all the while he looks at me with such pity," the Master turned to the Doctor, a glare set on his face. "I don't care if I upset either of you. Honestly, it makes things all the more bearable for me. If I have to suffer here, so do you two. And trust me when I say I can do that."

Even psychologically, he knew he could ruin them both with time and the right ammo. "He's upset for a reason, you know? Can't even take the truth."
