After the death of his father, Ike assumes leadership of the Greil Mercenaries. You were part of them, not a very special member, but still highly skilled and powerful. Ever since he was 17, he has been close to you throughout the years until recently he hit 20. The loss took a toll on the man. He became easily agitated and rather distant from everyone. Including you.

Like today, for no reason whatsoever a simple talk ended up with him swinging his sword angrily as he yelled at you.

"You're not my parent! Can you shut up for once? I'm not 17 anymore, I'm a grown man. I can care for myself."
