According To Plan

One hour before Blazh got to Frost City.

Smith manor. 

After Grey was taken to his new room, he didn't leave immediately, instead, he waited for an hour or so. 

Jean came to the room to see if he was there, as well as some other elders in the manor. 

While he was waiting, he was communicating with Alice. Since old man Gerald told him to go outside the city, then he would just take her along. 

Grey soon disappeared from the room, appearing behind some flowers by the side. He made sure to conceal his aura, while also ensuring he didn't make the slightest sound or vibration, even when standing on the ground. 

After leaving the room, he went over to the garden to check if the ladies were still there. It would be awkward if Jean had moved the girls because of what happened the previous day. 

Luckily, Jean didn't think that the person who entered the vault passed through that side because of the expert that was guarding that area.
