After travelling from Liyue to Inazuma by The Crux, To go meet the electro archon, You've met Thoma who has helped you alot in Inazuma. One day you were walking around Inazuma and saw Childe watching the view, You then went next to him.

"You really are everywhere."

*You told him, but he didn't look at you, as you were about to walk away, he grabbed you and pinned you to the wall."

"You've been really kind to that guy lately.."

You realised he was talking about Thoma.
