Cory Monteith

I wonder what this will mean for Glee. As far as I remember, he still had a part in the show.

Yeah, when the 4th season ended, he'd basically just come back and was set up to have a new storyline regarding co-leading the Glee Club and possibly getting back together with Rachel, which got sidelined when he went to rehab. His absence in the last few episodes wasn't explained in the slightest, he just disappeared. Which has put the show in a sticky situation. The entire point of his character was that he "wasn't going anywhere" and had no prospects, so it would be unbelievable for them to say he got a job somewhere far away.

The only thing I think they could do is to kill off the character off screen somehow... but I have no idea how they would do it that would seem believable. It's obvious they are going to do a tribute episode to him, so I hope it's a fitting send off.

As i've said before, I didn't like his acting or singing, and I didn't like his character (though he got slightly less annoying in the 4th season when he wasn't obsessed with popularity).

Regardless, the show will go on without him. The same way it went on without Quinn, Mike, Mercedes and Sam (for a while).
