[Katara frowns again.] I haven't spoken with this one. I know he went home and came back too, I don't know how much he remembers. He was on Diana's team - a bunch of superheroes, they called themselves. He worked with the Green Lantern and Superman.

I only met him once. It was [she pauses to think] right before you got here, actually. When everything was falling apart in the barrier and there were monsters everywhere. He'd been badly hurt - severe lightning damage and a bunch of cuts. But he was still coherent and conscious, able to speak with me.

Diana took him to rest after I was done, and I haven't seen him since.

[...she misses her.] But if Diana trusted him, I do too. You know that he was the one who made the cells in the tunnels, right?

[Katara doesn't feel the need to draw conclusions from this information. She's sure that Shikamaru can get the same that she did.]
