Tyssa stayed still as Lyre did the tests on her body, shivering a little at the cold stethoscope on her back and chest. She tried to hold back on breaking anything or hitting Lyre when the reflex tests happened.

She blinked at the Probes that were to go down her throat, she knew where they were going. Her ears flattened and she almost refused to open her maw, she slowly opened her maw to it's full length- rows of jaggered sharp teeth glistened in the florescent light. Her long tongue was tucked away in her lower jaw.

Her ears flicked as Lyre spun, looking towards the door as it opened. As the director stepped in and spoke to her creator; her instincts went haywire.
She stepped forward and fanned her wings out and flexed them around Lyre to protect her.
The experiment didn't speak, a low protective rumble echoed from her throat, watching the male with glistening eyes.
