"Yes, yes, you're safe now." Trinity kissed the top of Karn's head, right between his cat ears.  "I've got you right where I can keep you." She rubbed under his ear lightly before rubbing his back. However, when she sensed a flux of magic nearby, she thought she should make sure Karn felt safe. She raised a personal sized Energy Make barrier between her and the source of the magic activity, just in time to deflect the sound blast. With what must have been the source of what she sensed deflected, she dispersed her shield quickly. Perhaps she was being too paranoid, but...

"I hope you have some way of repairing the damage you just did to this train." She held a hand on Karn's neck, trying to stay his nerves before she turned to look at the troublesome mage. "And look how you've frightened my poor Karn with your antics, he's terrified! What do you have to say for yourself?" She kept her distance, not wanting to make him throw another fit and make things worse.
