[Honestly Tenma is two seconds away from shining a little light in Roland's eyes to check for abnormal pupil dilation, so keep doing totally normal things. Only propriety is keeping his medical kneejerk responses in check; were this not a fun party full of young people, the jig would already be up.

[Call him immediately, thanks. He should make business cards. Anyway, let him just park himself here in a seat, innocuously. Hmm!]

Is the pork platter your favorite? I'll take whatever you'd make for yourself.
