Jiang Fei and the girls were very skeptical of Z0-11's meeting with Jiang Fei. They believed that there was more to the meeting than meets the eye. But without any evidence, there was nothing for them to work with. As for 0543, Jiang Fei did not believe that it was possible for it to betray him, and what Ariel had was only a hunch. After all, Z0-11 came well prepared. Its device had countered Ariel's ability to detect electromagnetic waves, and also left without leaving any evidence behind.
But regardless of how puzzled they were about the meeting, they eventually brush the matter aside after considering the fact that 0543 was just created not too long ago. If 0543 had already double-crossed them, then Jiang Fei would really be at his wit's end. Even if he could just use his administrative authority to seal up the assistant, but wouldn't 0544 and 0545 also turncoat just as easily?
