You had a argument whit Eren after he came back from Liberio, he was much more distance as cold, so.. ruthless. Yet as you told him you don't need him, he said something that caught you off guard.

"You live a long time yet, an eternity whitout me, you will look into the faces of passengers hoping for something that will for an instant bring me back to you. You will find moonlight nights strangely empty because when you call my name through them there will be no answer." Eren said that blunlty, like he already knew.
