Answers after the break.
1) I like Spike. That aside, I think they were just dancing near each other, not with each other.
2) What do I care what humans do?
3) Everypony’s does. You take the bad and live with the good.
4) Well, ours is probably not the best example. I slowly began to piece together that Krastos liked me, including his comment that he had a crush on a pony. When I was almost positive, I just asked him if he liked me.
Best advice I can give is to spend time with them. Talk, make sure you know what you’re getting into. Ask if they’d like to go somewhere with you.
5) Probably the lyre. Always fascinated me.
And if the sarcasm is too thick, in addition to the lyre, I also play the sitar.
6) I don’t know any fire spells. It’s resolved anyway. For now at least.
7) This some hip new lingo?
8) I take it this is not some hip new lingo.
9) Gotcha, Boss-cov! Get it? Do you get it?
10) What are all of you talking about? Cave? Underground?
11) Huh?
Hold on.
