WWE just spoiled the outcome of a huge attack by revealing the identity of a mystery star. This comes after the star's identity was kept secret during the show itself.In one of the major matches of the night, involving Jacy Jayne against Lola Vice for the WWE NXT Women's Championship at No Mercy, a mystery attacker was involved. Vice had the match in hand when she hit the Spinning Backfist, but when she hit it, she fell out of the ring. This was when a mysterious hooded figure got involved. The figure appeared and hit Vice with a running knee strike at ringside. This led to the star being rolled back into the ring a moment later to be hit with a Rolling Encore, ending the match with Jacy Jayne retaining her title. Now, WWE has revealed that the hooded figure was none other than Lainey Reid. They accidentally spoiled the fact on their website when reporting what had happened during the show. As a result, they included that Reid was the hooded figure who had interfered.Reid had been pulled from the show earlier."Jacy Jayne retained the NXT Women’s Championship thanks to a shocking assist from Lainey Reid."Lainey Reid was supposed to be out with an injury at WWE NXT No MercyThe identity of the star has not been revealed in the storylines yet, as the hooded figure exited without revealing who was underneath.
