Oh please...for the love of all that's holy, do NOT make this guy Clara's love interest. PLEASE. I can't deal with another Amy-and-Rory situation.
Don't get me wrong, I really cherished Amy and Rory as characters, but towards the end of their time with the Doctor, the writers got more than a little heavy-handed with their love for one another. Every other episode crammed the intensity of Amy's love for Rory (or vice versa) down the viewers' throats. By the time The Angels Take Manhattan rolled around, I wasn't as sorry to see them go as I thought I would be. I just needed a break from the sappiness of it all.
Who knows? Maybe Danny Pink will be a really interesting character and I'll get to like him like I did Rory. But I don't agree with the idea of making him a love interest for Clara, especially if they're trying to use Danny as a way to keep the whiny Tennant/Smith fans placated because Peter Capaldi isn't the young stud they were hoping for. Having Clara become interested in a new guy after Capaldi takes the stage as the Doctor will paint her as being rather shallow, as she has been written as being quite taken with the Doctor while Matt Smith was in the role.
And, fine...if Danny Pink MUST be Clara's new love interest, let it start slowly and realistically, and for God's sake, don't make it a major focus of the new season. This is supposed to be Peter Capaldi's time in the spotlight; he shouldn't have to share it with another budding couple.
