Well--whatever it was, didn't seem like a threat. Yet. Swooping a few times as Lydia tried to make sense of it. It took her a moment, before she realized what it most likely was. Or close to it--a Covered Wagon!

It was a chance, but they needed it--badly.

Seeking more height, so she'd be visible and she looped a few times. Not in distress but trying to signal it was alright, she was alright, and this might be safety. Then she took another chance, and moved out a bit, before dropping to a safe-height and changing back to her normal form. "HEY!" She yelled, waving her arms at the...thing's direction. "PLEASE stop! Help us!"
