Thalia's actions were concealed enough that even her trusted members did not know her plans. She had to be cautious. While she trusted the members not to betray her, but under the control of a higher being, it was a possibility she needed to avoid.
At first, she had not suspected Mitchel or the Blue Guild, but after regaining her memories, there was a long list of reasons to suspect Mitchel of Rise's disappearance.
Not to mention Epsilon entering his guild, his feelings for Rise were also obvious. It was even more so when Kamille specifically targeted the Blue Guild, and Mitchel was nowhere to be found.
How could he not participate in finding Rise? There was no way. He had to be part of this.
She thought that since everything that was happening was not part of her memory, she needed less than a week or more to pinpoint where Rise was. To her surprise, she only needed a day!
"Are you sure you saw this Blue Guild member there?" Thalia asked through a private channel.
