Are we supposed to believe this?

Adrienne and Sarah are headed to the hospital from the mansion. I get the flat tire delaying them, but after that, how the hell did Maggie have time to drink nearly an entire bottle of vodka and catch up to them? Also, wouldn't Maggie have been driving in the same direction, not towards them? Will was going back to the mansion, so he was definitely driving towards them. I'm just not seeing how Maggie is to blame. And boy did it get dark fast in Salem? When Summer (useless character) showed up it was daylight and Adrienne was rushing Sarah out the door. Also, Sarah and mpMaggie had just gotten back from Brunch! It's like watching the Hunger Games and they change directions and time of day to fit what they ant to happen.
