This time their trip is spent in a relaxed atmosphere and upon their arrival the three travelers take a taxi to go back to the villa on the cliff by the sea, Umi no ie, where Professor Akira Sato and his daughter are waiting for them.
It is strange, at first, to see someone in duplicate but Mimiko Sato - the oldest - does not stay permanently at the house. She goes back to her work and returns mainly to participate in the procedures and to share her advice and experience.
Francis Blake has decided to try his luck and follow the treatment and, since Professor Sato has been warned in advance and has prepared all the necessary equipment, he is rejuvenated in the room next to the one where Mortimer himself has become younger - right on the other side of the wall.
Once Professor Mortimer - the one they left in London – joins them, Philip Mortimer takes good care not to venture into the house's common areas where he could meet himself during his waking phases. The procedure is serious and hence the constraint isn't too dire: the convalescent professor barely leaves his room.
While Blake follows this same treatment, Mortimer tries to ignore his anxiety by plunging into his work. In a part of Professor Sato's library set aside for two decades, he reconstructs Professor Miloch's time machine again. *
This time everything goes faster: he already has the plans and it is only a matter of mechanics. When it is finished, Mortimer asks professor Sato to pen the notice he must post on the door of this part of the laboratory back in the past: Do not use for ten years. This way he will make sure that in the present there is room to install both the chamber where Blake undergoes his transformation and the space necessary for the Chronoscaphe's construction.
During a period when his friend is unconscious, Mortimer makes the trip, leaving both Professors Sato in suspense in front of an empty room for a few minutes. He does not encounter any obstacle in this new expedition to the past and when he returns to his new present, it is with the relief of having accomplished all which was necessary to organize his adventure.
Towards the end of Blake's metamorphosis, when the latter has regrown a mustache worthy of the name, Mortimer takes his picture and contacts Honeychurch, both to inform him that everything has gone well and to ask him for the help he had promised for this last detail.
This is how he goes back to the embassy to bring in the pre-filled forms for new passports for Blake and himself. Honeychurch will ensure that they are ready in time and back-dated, so that Mortimer doesn't get into trouble when traveling in the past.
* No, Honeychurch does not know.
