Shavaughn literally just vanished one week without any mention, which was strange. Then she was back for the final show as if she'd never been away.
The strangest departure was H and Claire, as they presented it for six months and then one week it was just Tess and Brian presenting, but H and Claire were guests and performed their latest single, after which they said "H and Claire there", and made absolutely no reference to the fact that were presenting the show until the previous week, and then they never appeared again. Absolutely baffling.
It's like The Big Breakfast in that the show was so heavily based around the personalities of its presenters and then when they left there was a chasm, and then you had a revolving door of hosts who all lasted five minutes and you never knew who was going to be on. The Big Breakfast managed eventually to save themselves, for a bit, with Johnny Vaughan, but SMTV never found anyone to replace Ant and Dec. And they also did the thing The Big Breakfast always did, which was when presenters left they just abruptly disappeared and were never mentioned again, no matter how stupid it looked.
Of course, it was suppsed to be James Redmond as the full-time replacement for Ant and Dec, but it never worked out and he was soon out of the door. This was a real shame, I always liked him, and it wasn't his fault he didn't make much of an impact because at the same time he started they also hired Brian Dowling who was more famous than him, and got in all the papers, and it looked like they were trying to replace him before he'd even started. They'd have been better off keeping James and Cat on their own for at least a few months to allow him to get established before bringing in other hosts. Presumably they were having second thoughts and went for a throw-enough-mud policy.
