Which Glee Character Is Bi??

Spoiler Alert!!
One of your beloved characters on Glee could be coming out as bisexual!
And that person is…
Blaine!
According to sources, Blaine, played by the very delicious Darren Criss, will have “an encounter with a pivotal member of the opposite gender [in an upcoming episode] … afterwards, he’s forced to consider the possibility that he swings both ways.”
Hmm, we’re not sure how we feel about this. Blaine is written as a very confident gay teen who knows what he wants. Could this be confusing to viewers?
Thoughts??
