[Sephiroth isn't very good at picking up on others' emotions or on social cues, but he's more used to laughter with no apparent reason behind it than most people, so he continues to watch Zack gravely, eyes wide. He isn't sure if he said something funny, or if Zack is laughing for some other reason. He nods again.]

Thank you. I've never sparred with a SOLDIER before.

[He said yes! Sephiroth has fought against adults and monsters and holographic opponents before, but not a real SOLDIER. This is going to be the best. He can prove he's already good enough to be in SOLDIER himself.]

I was looking for weapons, but I haven't found any yet. [He can defend himself without a weapon, but he'd prefer to have one if he's on his own. He's used to fighting with a sword.] There must be some. It's a large town. [Nothing like Midgar, but large enough.]
