After everyone settled down, Heinz cleared his throat and asked Celine to take over. The two of them had collaborated in the past. Both knew that each of them were in possession of one Ciel's notebooks.
These were the instructions left by Ciel before he went into a coma. Ciel left the ones related to research in Celine's hands, while the contingency measures were left to Heinz. Heinz only need[ed] to say a few words for Celine to understand his circumstances.
Naturally, she would do her best to extend her help… even if they would have to weave a bunch of mumbo jumbo.
For this next phase of the meeting, only Celine--who had the "professional appeal"--would be able to make her words sound credible and scientific. This acknowledgement would hold true even if she was just explaining the bristles of a toothbrush.
