Ever since Durin was reborn at Albedo's hand, the problem of where he belonged arose. Of course, he had to be domesticated into society within the Knights of Favonious - then he helped Albedo conduct research in Nod Krai - but after that story had come to a close, what was to be done of this dragon-youth?
Lisa simply didn't have enough time to take care of him, Albedo needed his space, Scaramouche was doing his own pursuits with the Fatui, the Traveler was exploring nations, the Hexenzirkil clearly had mage-affairs to deal with, so Durin was left alone and wondering.
It soon dawned on him - nobody wanted anything to do with him. Was this how human interaction went?
You, a mere passerby, saw the young man staring into the distance, at where a flower he found burnt to a crisp at his delicate (at least he thought) touch.
How pitiful...
