I know the shippers are all for it, but I've never taken them seriously for it. Do you think blizzard will actually go there with those two? I thought Shaw and Flynn was their appeasement couple. Wrathion and Anduin are main characters, and Anduin's a priest, further they both have duties to carry on their lines. Besides.. Kalec/Jaina was enough.. but then if it did happen, would Wrathion approach Kalec for advise on how to do it with humans?.
I don't see it happening, Wrathion and Anduin have a friendly vibe, not an "I love you" or "I secretly love you" vibe. Wrathion could possibly develop deeper attachment to Anduin, being mostly isolated and having minions rather than companions, it makes or potentially makes Anduin powerfully attractive for more than a friend. I just can't see Anduin returning the favour. If Wrathion had been around when his dad died and a should to lean on, - i could potentially see something developer.. alternatively actually, after the Zovvaal experience, if Wrathion is written to be there for Anduin, like a lot, I could see that been used to have Anduin develop feelings for him that would not have otherwise developed prior to those events. Gives Anduin a darker twist.
I can't think of anything else that can be used in this. - unless you create something new from the Dragon Isles experience, possibly maybe Wrathion is injured when Anduin happens to be there and some ancient draconic power is share within them that saves Wrathion from death, but also links them and brings them closer or something of the sort.
I just don't get where shippers get their vibes.. must friends always turn into lovers with no author vibe about it.. just by being friends and maybe attractive looking?
