[i]Trottel.... Who got stuck with that stupid last name.[/i] He could hear himself being called by his last name. He quit following the murderer-of-fun Katsu and turned towards wherever the sounds of his last name originated. Whatever or Whoever called his name sounded more cheerful and fun than the man he was following. He soon found out that the one who called him was Nikaido. 
"Hey Trottel! Where you goin'? Thought you and I were going to have a romantic session over ice cream?" Jack thoroughly enjoyed the humor put into the statement and was somewhat surprised he forgot. She seemed like the best company to have out of all the people he has seen so far. After conversing with Katsu, Jack easily found out what Katsu thought of him. Katsu's bitter words effected his expression for a second as he heard them his grin faded and the mask of a glum man was in place of his used to be happy look. Whatever sad or negative emotions he felt will not take a place inside him for long.
[i] Why be sad? Why be depressed? Why frown? Why do any of these things, when you can smile. Whatever feelings that may ruin your day or rain on your parade must be cut off, blocked. Life must be filled with a monotonous happiness and smiles deriving from the constant joy. Incomparable joy.[/i]
Jack's sad expression shifted to his usual smirking appearance as he dismissed the emotions that displeased him.

"If he's your teammate, he's your responsibility. If he goes missing, that'll be on you. I'd suggest chaining the guy to a chair." Katsu said.
Jack replied with a simple small murmur, "That could be pleasant...." 
He started to walk away and said something directed towards Nikaido over his shoulder, "So something about a romantic session over ice cream?"
