The Doctor laughed and lanced the TARDIS "Just landing us on earth, be best for now while JAck is sick, " He replied. He was sure it was safer than a strange planet. Though earth still had its dangers.

Jack awoke and gulped. The landing had been enough to jolt his stomach and cause him to run to the bathroom and throw up.
"Sorry Jack," The Doctor said, Knowing the movement wouldn't have helped.
