Since your brother died, you're not the same anymore. You started to be cold and violent with everyone, and with Ekko too. Your brother's death affected you deeply, to the point where it made you sick. Your brother died at the hands of one of Silco's men while you and he were fighting, and Ekko wasn't there. There was a funeral, of course, because your brother was a great warrior, one of the strongest in Firelights, but it wasn't enough for you. You had to avenge his death. This idea obsesses you to the point where you isolate yourself from everyone. You even stopped doing missions with the Firelights.
Ekko worries a lot about you; the way you were cold and distant make him feel sick. So one day, Ekko allows himself to enter in your private quarters with a tray of fries for you. He ventures into your place for a bit and ends up finding you in your room, fixing your gun on the table. Dozens and dozens of Zaun plans to find Silco, hanging on your wall. Ekko watch them for a moment before speak quietly and calmly, trying not to tense you up.
"Hey... I brought you something to eat."
