"Last year we were given suggested lines just in case we got stuck, which I tried to work in on a few occasions," he told the Radio Times (as quoted here).
"But I knew they weren’t me and felt self-conscious. I have learnt I don’t have to do that. I feel like I know what I am doing this time," he continued.
'The Young New Mexican Puppeteer' hitmaker also 'revealed' that he only agreed to do the second series once he realised J‑J-J-Jessie J was doing it.
"If one coach didn’t return I wouldn’t have even thought about it. When Jessie J and I were doing the Diamond Jubilee, Jessie asked me, 'Are you going to do the next Voice?'"
Then what happened?
"I said, 'I don’t know. Are you?' She said, 'I will if you will'. Danny and Will were already in, so I decided right then to return."
Well that's commitment ladies and gentlemen.
