The other three had already come back from their exploration. There was nothing much left and they couldn't go check the underground area. There was an explosion within the lab and more than half were destroyed.
Those tubes and some rooms remained relatively intact but the information was limited.
They could only come back and perhaps figure out a way to relay to their contact about this matter. The laboratory might be related to the organization but it could also be related to others.
No matter which one it is, they should check.
"Have you finished with the report?" Miro asked when he saw Arya coming back again. Even though he was curious about what the other party said, he will not try to pry for information blatantly.
What Arya had told him so far was only things that he was allowed to know. Her control over the information was really strong, so Miro could only test occasionally to see if she was allowed to tell them some things.
