Klaus had noticed just how much all this was getting to his little brother. Possibly the most perceptive of the Mikaelsons when it came to Henrik. Klaus followed him from the reception, staying a little behind, using stealth as only the Original Hybrid could. He needed to gauge if Henrik would rather be left alone, in which case Klaus would give him that. he didn't want at all to crowd the boy. Adjusting to this world, to this time, it was proving hard for him. That and learning the powers he possessed, those of a witch. Klaus hated it of course, what those powers represented in a Mikaelson, and that he'd already had the thought of how best to use them to further their aims.
He was, after all, what he had been made.
And the death of the boy now sitting by his treehouse had been the catalyst.
Finally deciding to speak. Klaus stepped out of the shadows and cleared his throat. "Henrik." he said simply, moving across to sit near him.
"Hard to watch isn't it? She's happy, she's radient even, but ultimately she won't be living with us now. Thing is, and believe me, this took me a thousand years to get my head around, it doesn't mean she's leaving us, or that she won't be our Rebekah anyone, our sister. That doesn't change with this."
