Didn't you say someone bad was there? [ or maybe a version of someone bad that Katsuki knows. Kaneki finds himself stil clinging to the other as he speaks, looking down at the ground ]

Do they know what is happening? That you are not this world's Bakugou? [ kaneki frowns a little ] Because... won't they try to kill me if they see me? [ this world's kaneki does not have a good reputation- which is VERY fair! But he doubts anyone would just welcome him with open arms ]
