Nevel didn't return, and I think Chuck's story was wrapped up in "iBattle Chip"

Nevel's closure should of been iPity the Nevel. Bringing him back for iHalfoween was extremely unnecessary and only left him with potential to return again that never came about.

I remember Mandy, I remember an array of characters they could of fit into the finale, but I guess some would of just made no sense and would of intruded upon the plot.

Plus the actor IS old enough to possibly be Spencer's dad. At the very least Spencer's dad could be 20 years older than him, putting him at 50. My dad's still got full brown hair, doesn't look that old, and he's 60!

Did anyone notice at the very ending scene of this episode, there was a car driving by with "iCarly" on its license plate? Very touching .

I just had a look at how old some of the actors are in the Shay family.

Granddad: 73, he is played by Greg Mullavey
Dad: 41, he Is played by David Chisum.
Spencer: 35, he is played by Jerry Trainor.
Carly: 19, she is played by Miranda Cosgrove. There is a 32 year gap between the Granddad and the Dad in real life. But there is only 6 years between the Dad and Spencer, 22 years between the Dad and Carly in real life.

Going by the actor's age, not the character's age.

Hah, well, with the rate people are getting pregnant these days it wouldn't surprise me XD

As recurring and minor characters go:

Chuck: I agree. His story kind of wrapped up when Spencer reveals that he was sent to military school. I really enjoyed his decisive character during his time on the show (from seasons 2-3?). His little brother was a huge rip off and had nothing on Chuck; I was kind of glad to see him be outsmarted in just one episode appearance.

Mandy: OMG I LOVED HER. Mandy may have seemed annoying to the iCarly crew, but she's hilarious. QUACK QUACK. Event though she only appeared twice, she does justice when she's on the show. The thing is though, the actor who plays her hasn't been around much. When she appeared she was starring in movies as "Roxy Hunter", and now those days are gone. I suppose Mandy's last appearance was decent, since I can't see her character going to many places.

Nevel: Man I do I despise this guy a lot; but his episode from last year was really touching, and I wished they had ended his character at that point. What a spectacular and decent conclusion to Nevel. But Nope. The iHalfoween was an interesting idea, but it was pointless. Not to mention it plummeted in ratings. They were really milking out Nevel's "revenge" vibe which got old very fast.

T-BO: This guy's cool, and he's funny at times. I kind of wish he was added to the cast for Season 6-7 since he technically did appear more often and was a hero during iStill Psycho

Principal Franklin: This guy wins Principal of 2012. I wish he could have appeared at some point, but then again, the show was dishing out a scarce amount of new episodes. That restaurant episode served him well, and at least he allowed Gibby to keep it open (Who knows if its still running or not).

Mr. Howard: This guys a chip. I dont like him at all; but he was okay during iparty with victorious when kids laughed at him for saying Colon Pee.

Missy: ...I am so glad they got rid of her in just one episode. I don't feel remorse for her when she was puking on the ship. Plus, Sam snagged her phone! HA. Take that... bad word.

Valerie: One time character, but I'm glad she was off one episode. She also doesn't got anything on Missy since Valerie is just pathetic. Seeing her at the end of the episode made me giggle. "Oh, how silly it is of her to think that doing a webshow would be easy."

Wendy: YES. This is one of the nicer girls at school, and a close friend to Carly, Sam and Freddie. I'm glad she appears often, and she's a better friend than Missy. I really liked having her around on the show. Just wish she'd appear more too.

Ms. Ackerman: I miss this lady; she was so funny in just one episode. She would appear more if she wasn't in custody under the FBI.

Pete: What happened to this guy? He and Sam kicked it off really well, especially when she kicked the 3 senior girls' butts at the Groovy Smoothie. I thought he could have been a great boyfriend for Sam. But then again, Dan doesn't wanna touch relationships a whole lot.

Tasha: I'm so glad she only appeared right after the first part of ONE episode before the opening. What a close minded character. KICKING HER OFF THE SHOW. Best thing ever.

I still miss all those other minor/recurring characters from season 1. Like Ripoff Rodney, Duke, Wesley (beat box boy), Jeremy "Germy", Shannon (Gibby's crush), Tareen (the girl who talks so fast), and heck, even Ashley Argota's one time character! I don't care if she was going to be on her own show with Keke Palmer; Ashley could have appeared more.

Well, Wesley did appear during a season 6 episode, but he was played by a different actor. Was he... a juvenile? 0-0 I'll have to go and look at that episode again.
