Humongous Growth is the 4th episode of the fifth season and the 102nd overall.
Following the events of the previous episode where Will throws Grace out of the apartment, Jack and Karen discuss at how things have gotten difficult because of their separation. They create a plan to get them back together by separately inviting them to the birthday party of Joe and Larry's daughter Hannah and "win them over".
At the party, Will and Grace fight again and refuse to talk about resolving, until Jack and Karen throw them into the balloon moonwalk. With no choice but to confront each other, they realize they still want different things. As Grace walks out, Will tells her that he still wishes her new relationship with Leo to work out. Touched by their love for each other still present in spite of everything, they apologize and hug.

|Will:||I got Hannah a little something.|
|Jack:||It's from both of us.|
|Will:||It's actually kinda cool. I adopted her an endangered panda from The Discovery Store. You get a certificate and a pamphlet about the threat to the environment.|
|Jack:||It's from Will.|
You need to go over there and make nice with Joe and Larry. You don't want them going over to Will's side. They're gay. They belong to you. — Karen, to Grace
|Jack:||So we need to get them back together. But how? Pretend to think, pretend to think.|
|Karen:||Pretend to care, pretend to care.|
|Will:||Nice going, Grace. Our friendship, a kid's birthday party, your over-processed hair. Anything else you wanna destroy this week?|
|Grace:||I don't know, anything else you wanna blame me for, you big bitch?|
|Karen:||This plan bites!|
|Jack:||It's better than yours--telling those kids those balloons are made of candy.|
|Karen:||Hehe. Kids are dumb.|
|Jack:||I know. I ate a balloon, it tastes nothing like candy.|
|Grace:||Was Leo the right guy for me? I don't know. I don't know if it's gonna work out. But I hope it does. And I'd hope my friend would want that for me, too.|
|Will:||I'm sorry, Grace, but it's not that easy for me.|
|Will:||Because it's not.|
|Will:||Because I need you more than you need me!|
You know what I really want? I wanna do this the old-fashioned way. I wanna meet a guy, fall in love… Quit going to the gym, 'cause I met someone.
And then make a baby. — Will
|Will:||You just met the guy and you picked him over me.|
|Grace:||I couldn't pick him over you because you are not an option for me!|
You guys' friendship means something to me. It means that maybe we don't have to be alone in the world. That some things do last forever. That a fatty and his enabler can find love. — Jack, on Will and Grace's relationship
