טקסט מקורי - אנגלית - Who then now?

Isolated words?

HI. You were faster than I; Have a break.

Hi girls,

We can consider this one as an ellipse of the complete sentence "Then, who is now?"
We'll let it go.

Thanks anyway.

I wasn't sure either...the rules for "isolated words" are a bit tricky. Thank you Lilian!

Hello BikerBoyZ,
What does this mean, please?
Please write an equivalent full sentence in English, and/or give the context for it: the previous and following sentences, etc...?
I can't translate it into Japanese if I don't know what it means...
