That was in the time period between Russo's booking stints, when Kevin Sullivan & co. were in charge.
Some of these turns are just mind boggling. I do NOT remember Bret Hart joining the New Blood.
I remember Hart coming back and helping Lance Storm I believe, but nothing with the New Blood.
He didn't help him, Lance Storm won the US title on a PPV and Bret came down after to congratulate him, nothing was out of the ordinary, as it was in Canada and Bret made his return.
