[Sheena moving past Vincent was noted, and he hoped she wouldn't do anything too reckless or rash. Elena was clearly spooked--and knowing what he did about Sephiroth, Vincent did not blame her. Nor had it been clearly established just when they were yet. He wasn't certain if the blonde turk would consider him an enemy or not, regarding his affiliation with Avalanche.

Keeping his eyes opened, he shifted position smoothly as Sheena moved Elena via her ninja Job-skills into the cave. Pivoting in his crouch, keeping his firearm out and trained on Elena. Of course, now Elena could likely make him out against the cave-wall, weapon trained on her. Just in case, in addition to Sheena's seals.

No need to really hide anymore then, and they needed to all calm down.]

Elena, I would believe her.

[Besides the fact that Vincent had his own gun trained on the blonde and wasn't known for hesitating. This would be the only warnings the female turk would likely get.]

Your panic is understandable. There are different circumstances at play here, however, that require him alive and unharmed.
