Freedom crossed her arms and leaned back in her chair.  Tommy looked back at Freedom and then back to me, shrugging his shoulders.  Freedom stared at me like I might disappear if she looked anywhere else.  I finally asked, "Freedom, is there something I can do for you?"

She was twisting her hair between her fingers.  I could tell she was pondering whether she wanted to say something or not.  She looked across the room at Tommy and then back at me.  She was a pretty girl with very tan skin.  She flipped back the blue feather in her hair and then pushed the rest of her long black hair behind her shoulders.  Finally, she spoke and said, "He never left."

"Excuse me?" I asked.  "I'm not sure I understand what you're referring to."  Actually, I knew exactly what she was referring to, but I decided to play dumb.

"Liberty, he's still in the room: she calmly said. "I can smell him.  Horses have a strong scent.  And if you look closely, you can see his image outlined against the back wall."  Still sitting at her chair, she turned around and traced Liberty's outline with her finger.

"I don't see anything," Tommy said as he strained to see what Freedom was pointing at.

It was apparent that Freedom had a gift.  She acted as sure as if she were pointing at the sun.  Questions raced through my head.  Could I trust these students about the time-travel abilities that Liberty and I enjoyed?  Would they be able to keep the secrets about our historical missions?  I decided to take a chance and said, "As I mentioned earlier, Liberty is an extraordinary horse.  In addition to his language skills, he has the ability to disappear."

"Not disappear," said Freedom.  "He's blending into his surroundings like a chameleon."

Suddenly, Liberty reappeared right where Freedom had pointed, gasping for air.  "I couldn't... hold my breath... a second longer," said Liberty, still trying to catch his breath.

"What the...!" Tommy exclaimed.  He looked at Freedom, then to me, then back at Liberty.  "Did he just appear out of thin air?  That's awesome!  I mean, that's the coolest trick ever!  How do you do that?"

Explaining the impossible is never easy, but I tried my best and said, "Soon after Liberty and I met we discovered that when Liberty holds his breath he can turn invisible.  Well, he's invisible to most people," I said, glancing at Freedom.  "It's sort of like when you hold your breath and your face begins to turn red or even purple.  When you let out the air, the color in your face returns to normal.  It's the same principle with Liberty."
