However, I think it is important to note that does not mean that this is the 5th time that Jenna has received the lowest amount of fan votes. For all we know, Jenna may not have received the lowest votes any of those weeks, and Nigel really did not "save" Jenna at all! That may have just been a dramatic play on his and the show's part.
Again, however, last night whether she received the lowest votes or not, it may be a case of "the boy who cried wolf', and Nigel has now played that one too often, and the viewers have lost patience with it as evidence by his remark about the tweets. It is obvious as well by the fact that she has been in the bottom so early, so often, that she is highly unlikely - no matter how highly Nigel thinks of her - to win the top spot as determined by the voters.
She is, nethertheless, in my opinion an extremely good dancer, and I wouldn't be surprised to see her end up perhaps in someway on DWTS somewhere down the line.
