ABC's summary of episode 2..
"Gabrielle goes to great lengths to hide her affair, Lynette tries tough love to discipline the twins, Bree and Rex attempt marriage counseling, and Susan musters the courage to invite Mike Delfino to dinner, only to have Edie horn in on her big night. Meanwhile, the ladies can't decide what to do with the disturbing note they found in Mary Alice's things."
I'll fill in the blanks..Gabrielle and John almost get caught by her husband so she decides they can't continue the affair at her house..they start it up at his house when his mom is away
Lynette's tough love is forcing all the boys out of the car when they're misbehaving (which is always) and driving off for a couple of seconds to scare them. However one of the neighbors sees this and wants to call child services on her till her boys push the lady out of the way and they all run back to the car and take off
Pretty funny scene
Bree and Rex marriage counseling..well Bree basically doesn't discuss her feelings at all till she ends up meeting the counselor alone for one session and while repairing a button on his coat basically admits she doesn't like that no one ever thanks her for what she does. The counselor brings it up in a round about way the next session to Rex and Bree is all happy
Susan sets up dinner with Mike but then Edie finds out and weasels an invitation as well. Long story short Mike's dog ends up swallowing Susan's earing and has to go to the vet lol. Susan shows up at the vet to apologize to Mike and ends up realizing that he's still in love with his deceased wife so she might end up backing off and just being his friend.
