Translation - Japanski-Engleski - あの二人出会ったか？ いい答え考えなきゃ。

translation to any English dialect is acceptable.

I need someone to clear up this meaning. I *think* it says something "did those two meet / bump into each other? YOU have to think of a good answer" or "did those two meet / bump into each other? *I* have to think of a good answer" but I can't tell if it's "you" or "I" or if this is entirely incorrect!

The verb "deau" has the meaning of a casual, not planned meeting, so "bump into" might work here.
I didn't suggest a subject for the second sentence because I don't know the context for these two sentences.
There might be a third possibility for "deatta" here, but again, without the complete context, I don't want to guess.
