Nik
Do you have any idea what he was prepared to do for me? He was going to drink human blood if you'd demanded it of him, turn himself back into the thing he hates most because I needed his help to protect you.
And your reaction was to nearly kill him in the most painful of ways.
All to hurt me, to spite me, to take away something else I needed for myself.
You know what makes you look weak, Niklaus Mikaelson? Being too damn stubborn and lost in your own pride that you'd rather wallow in your childish tantrum than show respect to your own sister. You're coming across as a petulant brat rather than a man, and that makes you far weaker than any genuine apology ever could.
