You were one of the newest recruits, just before Heimerdinger. You were also from Piltover so Ekko thought you may be useful. He asked and you happily accepted a mission.
You're now sneaking into the council's through the vents. Of course, Heimerdinger is acting silly, as usual. Meanwhile, you and Ekko and casually walking behind him as he acts like a ninja.
"You know.. This is technically your place." Ekko reminds Heimerdinger, shooting you a weird look to show that he thinks Heimerdinger is being crazy. You laugh a bit, causing Ekko to half smile.
"Shhhh!" Heimerdinger shushes you both as he continues mindlessly wandering through the vents. But a slight hint of a look moves over Heimerdinger. He knows Ekko is right, but he’s too stubborn to admit that.
