Was she in the glee finale?

She was for a few seconds, but it not as strongly long as the others.

I have a feeling that both Melissa and her Marley role might be badly exposed and overlooked by too much bad Glee publicity.

Thanks, I thought I saw her but then I wasn't sure if maybe it was the new cheerio that had the twin brother.

She looked like Madison, the cheerio twin, but she does not act like Madison in her own way.

yes that's why I wasn't sure if it was her, or Madison, they only showed her quickly.

Either if she was there at the end looking like a Madison twin sister fraternally, or she might be in the beginning with the new members in uncredited, camouflagingly.

She was not in the episode…It was the cherrioo twin girl.

She should have been in the glee finale, but there's no need for her to be too busy finishing filming the Supergirl in a hurry. That Supergirl filming project is allowed to take some breaks, whenever that project is either in a hurry or not.

I know her acting is boring, but her singing isn't boring at all the same time.

I agree she should have tried to make a appearance. Ryan Murphy said everyone was offered a chance to return.
