If there was any similarity to the Forest Trolls that Jin knew of, it would be that they have a high regeneration rate. Even though the Grey Bears were not reporting back to Jin, the System still updated the commander and now, the Interim Leader of Daimon City on the team's progress. It seemed like the Grey Bear Squad had decided to be self sufficient and not consistently rely on their commander.
Jin understood that Yinn might just be a Mechanoid but so far, she had possessed talents in leadership despite the lack of unique skills that the others might have. Even Diaz had been considered normal in terms of the standard set by the other Mechanoids within the Grey Bear squad. However, the System deemed that she might be able to find her speciality soon enough considering how she started to mimic Lynn and risking her life going for close quarter combats.
