Much like most of your respondents, I now crave sushi. Thank you for that one, master Hamada.

[Raw fish might be an issue in space, though.]

No, I'm afraid your friends probably aren't here. The nature of things like the Ingress are- whimsical, to say the least. But I have found that once someone from any given world turns up, there's a better chance of others turning up too. You might be lucky- or unlucky- enough for them to turn up yet. Or you might meet your worst enemy, or a face from the past you'd rather forget. And they may not remember you.
