All the leads, Clark  and Hal are there.

"Hal you have to be kidding me, some little green man said he was taking people back home, as if they have a shuttle service here."

Zoey sees Hal and Allura and smiles wide, "Hey!  Look who we found!  Hal, Rory meet each other.  What's this about a shuttle service?"

Hal, "I am serious and he wasnt little but he was green. He took the other aliens home and said he would be back to take us to Earth."

"I know it sounds crazy but I am being honest !"

In reply to Watchtower (msg # 4):

"I believe you Hal.  After everything we go through, how could we not?  So how long do we have to wait?"

Hal shrugs, "I don't know he didn't say. I guess you took care of the bugs."

Hal waves to Susan, "Glad to see your ok." He also says, "So your Rory, heard a lot about you."
