Plot hole: Jack and Joey are desperate to get the tank pump fixed so they can put the lobsters back in. However, once the customer tells them how to fix it, they then stop for a chat, check his table for tips, read a poem, share a moment, and start cleaning counters - with no attempt to re-house the lobsters.
Plot hole: During this episode, Jack is at Joey's house at night for some time. Pacey and Andie obviously spend a great deal of time together that same night with dinner, a walk and the Bed & Breakfast session (and we later find out they stayed there much longer than it looked originally). It has been mentioned in the past that Jack and Andie have to 'take turns' watching their mother, and they can't leave her alone at night. Therefore - while Jack is posing for Joey for much of the evening and night, and Andie is out on a date for much of the evening and night; who is watching their mother?
Plot hole: Season 2 picks up with everyone still in Sophomore year, which continues until the end of that Season. So we are presumably well into the Sophomore school year, and yet during this episode there are suddenly elections for the Sophmore President and Vice President. It doesn't make sense they would wait until this far into Sophomore year to be electing officers *for* the Sophomore year! Too much time has passed; normally elections like that would be held at the beginning of the year so the people elected can do their jobs longer, for the entire Sophomore year.
