Okay I've been sitting on this since the original post but... Who the hell gets out of an SUV at a gas station to publicly make out with someone they're trying to hide? Who makes out at a gas station in the first place? Why would Tom and Lizzie both be getting out of the car? Were they pumping gas together? Why them instead of the driver? I just don't think that story makes sense.

Do I think there was something going on between them? Probably. Is it still going on? Maybe. But I don't buy the gas station story for one minute.
