Lost
Only Sam could get lost in a museum, even if it was the biggest one in America. To make matters worse, his cell phone was dead so he couldn't call for help.
It was just supposed to be a simple tour of the building, he hadn't counted on accidentally being separated from the group.
His frustration was mounting by the minute, and it didn't help that he could sense Bee and Optimus's constantly growing concern.
As he came to yet another dead end near a bunch of really freaky-looking dolls, he knew that no one was ever going to let him live this one down. If, of course, he ever managed to find the Primus damned exit.
