Now I'm pretty sure I'm not the only one who's noticed this, but it's an observation of mine how for gojo "the strongest" stops becoming a description of his power and starts becoming an Identity......
At first him saying we're the strongest with him and geto is him describing his and geto's abilities.
But slowly and steadily it starts becoming an identity especially when geto leaves.
This whole panel shows geto asking him exactly that.
Even when the people around him are asked to tell who satoru gojo is while they tell their respective relations to him one important thing they all say is that he is the strongest.
When you're asked who someone is you respond with their identity. And them saying gojo is strongest is further proof of how strongest has become gojo's identity
That is what it's soo heart breaking that when geto's girls ask him who satoru gojo is he responds
It's soo heart breaking that geto the only one who doesn't add the strongest title to gojo is the one who isn't by gojo's side.....
