The REAL bae of Homeland Season 4. Quinn hew? BYE.
ELLE seems to agree with me as they sit Raza down and ask him a few questions about his experience working on Homeland as Colonel Khan. When asked about the perceived chemistry between his character and Carrie's, Raza had only this to say:
[...]Homeland really is one of those shows where they start to write more or less depending on what's kind of going on in a relationship between characters. That's what's nice about our scenes together, actually, because rather than an obvious attachment between the two of them, it's brilliant in its ambiguity. And never say never about the Carrie and Quinn thing, either.
He also comments that his character isn't as tightly wound as he appears, and perhaps he just needs Carrie to 'mess him up'.
When asked about the ending of this season, he commented:
I can tell you that things certainly aren't going to end well this season. Not to be a pessimist, but unlike other seasons of Homeland, there really are no heroes this year. I don't think that's kind of spoiling what's going on, but it's dark. Particularly at the end of episode 11, there are some consequences of stuff from which there's no coming back. Like I said, no heroes. No one steps in to save the day on either side.
(OMG PRAYER CIRCLE FOR SAUL/CARRIE/KHAN...)
