"There is no sign of any alien vessel on the planet."

"As things turned out, the alien vessel was looking for us."

Still, the alien vessel just sat there and continued to fire at the capital, as if her commander weren't the least bit concerned.

He'd been on enough hostile alien vessels to be ready for anything.
