Several reasons, Nelly Nut comes from TC2 and needs to rehearse during that time (and do some pre-rec in the case of Nelly).
Do they come from the studio or a room near by? I imagine the software needs more than the average PC!! The hand movements etc must be very complicated.

How does Nelly Nut work? I was under the impression it was done live...
When I get chance I only watch Nelly Nut because I think it's so clever!!
For the person who wanted her name, it's Rebecca Sheeman (I think). There are credits on Friday. I think see styles Nelly' hair
On pre-recs over the summer, CBBC TWO recorded the earlier links. I got up early one Monday and a viewer had written in asking why Angelica was still there because on Friday she said she was going to LA for a week, tomorrow. The other presenter then blamed the viewer for writing in, saying they had offended her and she had gone home, so Sophie had come in.
They may not have intended it to sound serious, but it did.
So now they are getting at others for their lazyness. I seem to remember the last 5 or 6 years every other team has managed to make it in for 7!
