Anon is correct - Franchise Herald is one of those click-bait,online-only sites that rehash articles from other sources. Others are Venture Post, Christian Daily? - there are a lot of them.
Unfortunately, some people think that these articles = TH or EO PR at work. Not the case. We can debate about US Weekly/Just Jared and even the DM being official mouthpieces, but these sites/articles aren't worth the time.
There are some people who think that these articles are leading up to an engagement/pregnancy announcement. Well, anything is possible, I guess. But either of these are highly unlikely. I know that Cumberbatch last year was a game changer for fandoms, but BC '14 is not the norm.
If there is a sloooowly blossoming relationship (shoulder shrug), we might get an idea of it at TIFF - maybe they'll be seen together outside of official events, maybe they'll walk the carpet together, maybe one will make a comment about actually being in a relationship with the other (shock, gasp!) Maybe, they'll show us if they show up at the Calgary FF - they will wear matching western wear as a sign to fans, obviously.
