Probably because everybody just asked about the next big thing when he showed up, and now that iSS has been revealed he can have normal conversations. And when they start asking questions about iSS he just spams the same explanation until they shut up. Seems like a good deal to me.
I noticed this too. Lol.
I'm not Superman, that's for sure. And I'm not Batman, or Spider-Man, or Aquaman, or a merman, or a wolfman. I'm not a brahman, or common, or ramen. I'm not a caiman either, so you really don't need to worry about anything.
