Hi again. As long as rules require to group questions by different topics, I've written that as separate questions.
So.
1. If Puck is Oberon's servant, why can he be summoned by Titania's mirror? Not some Oberon's possessions, but Titania's.
2. Does the spell, that Demona used to summon Puck, have any translation? Was it in Latin? I failed to find it on Wiki.
3. Why didn't Oberon just use the mirror as Demona did in order to summon Puck? Was he just in a mood for stroll?
4. In the way I see it, there's kind of tension between Puck and the Weird Sisters, as they say they can hunt him down for Oberon. I mean -Hunt-. Not to bring him, not to call him, not to remind to him. Hunt him down. Why? If this IS a spoiler, please, just forget you've read 2d question. If I just dramatize, feel free to tell it in any form you like.
5. Would - if heard - the ringing of the iron bell be at least painful to ANY one of Oberon's children in their true form? If not to all, then to who will it be?
