Nice! Okay, so I'm trying to think of what time-changes were caused by Clark's "you were drugged" intervention.
1)
Lois and Charlie interacted (obviously), with Lois finding more and more about his powers including Charlie is not his real name.
2)
Lois investigating the footballers a second time. I'm guessing in the original timeline whatever untoward might have happened to Lois at the party, the footballers would have left her alone after that and she'd probably have thought she got drunk.
3) A potential news
story on GHB and other date rape drugs penned by Lois Lane (if she survives her break-in at the stadium)
Oh and, does Lois still have Charlie's jacket with her?
