Shepard passes out.

With a last shot Shepard felt everything going dark.

She laid on the top and was out cold.

"She did more than I thought." Kasumi smirked.

"Never bet against Shepard when she drinks." Ashley said very clearly. "Good work."

"It was easy." Kasumi shrugged. Switching Ashley's drinks with water wasn't difficult. "Well now that she's out what's the next part of the prank?"

Ashley grinned.
