So how I know the prison scene is from iLove You We've just see the new promo for the arc and other brand new episodes. Here are the pics if you haven't seen plus a pic of Uncle Carmine
http://www.imdb.com/media/rm2881535488/nm1197237 this link shows a picture from the ICarly and if you look on IMDB Jim Giordano, who plays Uncle Carmine only appears in 1 iCarly ep iLove You
http://www.imdb.com/name/nm1197237/ Scroll down and you'll see it lists iCarly in this work and only 1 episode of iCarly iLove You, again I say as Uncle Carmine.
And a little something-something for other Seddie fans Why would Uncle Carmine's cellmate say, "You just be good to our Sammy" if they weren't together in ILove You
