Plot: When they are asked to read at the civil union of two friends, Will and Grace verbally spar over her self-serving, get-and-take attitude where Will is responsible for everything -- but what's really bugging him is the overwhelming feeling that Grace is behaving more like a wife than an old friend. Meanwhile, Karen tries to help a caffeine-addicted Jack get over a failed crush but he's so jacked-up on java that only a tough-love approach will work
