[Hearing Phos before he saw them, Bart lets out a yep at the sudden unexpected voice, jumping slightly. When he turns toward in their direction though there's a moment of confusion at the still mostly unfamiliar figure, before his expression finally lights up with recognition.]

Hey! It's you!

[Unlike Phos, Bart chooses to show no caution what's so ever. With speeds that were just a little too fast for your average human, but still felt far too slow to him, he zipped over to the half-crumbled wall and with a slight bound, plants his palms on to the craggy surface, pushing himself up off his feet and probably getting a bit too close for comfort. ]

Phosphophyllite, right?

[And just as quickly as he came in close, he's backing off again. Tipping back, he lets go of the wall and lands lightly back on his feet. Not catching on to the fact that, unlike last time, they were speaking Japanese, he keeps right on speaking in English.]

Oh, man! I thought that whole thing was some kind of weird dream or something. Are we back in the same place we were before? Is this the nerd book?

[He's speaking a little too fast, even for someone that would actually be able to understand him, and the stream of gibberish comes with gestures. So many excited gestures. He's grabbing at his hair when he talks about thinking it was a dream, does a quick spin around in a gesture at the area around them, and finally points to the ground when asking if this is the 'nerd book'.]
