Corrected entry: During the wedding, Andie spots Jen and Abby 'crashing' the wedding. She yells at them, and makes them leave. On the way out, Abby grabs an available bottle of champagne and takes it with her outside. Later, Jen and Abby both drink from this bottle; behavior which leads to Abby's death by drowning. It's illegal for a person of any age to carry alcohol from the premises where it is served, outside. It's also highly illegal for minors to drink and take alcohol with them from the same location. In this case, underage drinking led considerably to the death of a minor. Normally the institute that served this alcohol would have been in considerable legal trouble for serving (allowing) alcohol to minors, allowing alcohol to leave the premises and be taken outside, and also providing the alcohol that ultimately led to the drowning death of a minor. Whether the institute responsible was the club hosting the wedding, or Joey's family catering business; either way there would have been serious legal ramifications including the taking away of a liquor license. Yet in the show, none of this ever happened or was mentioned. It's also unreasonable that Andie's character, being very conscientious about rules; wouldn't have seen Abby take the bottle of champagne, and not allowed her out the door with it. Andie would more likely have grabbed it back from her and stated emphatically something to the effect of "it isn't legal to take alcohol out of the premises, and you're underage anyway" since she's such a stickler for doing things by the book. This was obviously overlooked as a plot contrivance, in order to allow the story of Abby's drowning.
