Another mutant might have missed it.  Most of the others at the wedding were not the possessors of augmented vision, however.<br/><br/>Petra wasn't quite sure WHAT she had seen, because when she turned her aquamarine-crystal eyes on whatever she'd seen it was already gone, but she had definitely seen something.  She believed it with the conviction of a bonafide egomaniac with absolute trust in their abilities, a trait her mother had deplored breaking her of.  It was far enough away from the activity of the wedding that it wasn't an immediate threat, no matter what it was, but at the same time, she couldn't simply move to where she'd seen it.  First the thunderclap generated by her power would alert everyone in the place that she'd left, and that would be rude to say the least.  More importantly, her outerwear would be torn to shreds by the apportation, and she'd spent a pretty penny to have the shirt and pants tailored.<br/><br/>As a result, she was forced to walk towards the edge of the wooded area opposite the mansion, her alien eyes shifting and quivering as she altered them to focus on the trees and treeline in detail that none of the other guests present could likely manage.  She didn't spot anythign out of the ordinary yet, but she was absolutely certain something had moved in the treeline, and anything that was trying to hide was not likely to be friendly.  At the same time, it wouldn't be worth alarming any of the other guests if it turned out to be a squirrel.
