If only Rodney had realized that Sheppard had slipped the chili peppers into his drink. If only Sheppard, unbeknownst to everyone, hadn't slipped them in, no one would have been able to see Rodney turn red in the face and run from the bar screaming. Soon, they would be able to see what a terrible thing Sheppard had done. If only Sheppard would realize what a mistake he was about to make. If only Rodney hadn't come into the bar. All of this could be avoided, if only they would open their eyes to what was about to happen, Rodney might have been saved. If only he could be saved.
Why was Sheppard doing this to his friend? Why would Rodney trust anything Sheppard would put in front of him? Why could the others not see what was about to happen?
If only none of this had ever happened.
"Hey, McKay. Want a drink?"
