Corrected entry: While watching the tapes at Jeff's house, he shouts "caffeine!" over to Erica, saying in a manner of speaking he wants some coffee. Erica leaves to go make a pot but looks through Jeff's fridge/freezer instead. When she comes back upstairs after the 'love scene' in the kitchen, she tells Kim and Jeff "We're out of beer'.

Correction: I keep my coffee in the fridge, and my brother keeps his coffee in his freezer; it is supposed to keep it fresh for a longer time. As far as the beer goes, she may have noticed while looking for the coffee in there that they are also out of beer. Another explanation may be that his interpretation of "caffeine" may actually refer to beer. Whatever the reason, it can't be ruled a proper mistake.
