While on a walk you go down a street and you hear talking in a nearby alleyway and you see Toga, Dabi, Kurogiri and Shigaraki talking about something

Toga: When are they going to be here!

Shigaraki: Just be patient! Give Kurogiri and the others time!

During this Dabi is resting against the wall listening to the conversation and Kurogiri is in the background doing.. Something..?
