Idea: the bats give the villains a way to contact them after they realize that since many of the villains compete for resources, it would be in their best interests to report their competitors.
This is a very important idea because it comes with the image of Two-Face and Penguin yelling at each other in a back alley, deciding to report each other at the same time, and diving for their phones. Cobblepot frantically scrolls through his contacts while Harvey screams HEY SIRI CALL BATMAN into his speaker. If only they had put Batman on speed dial
Many that live deserve death. Some that die deserve life. Can you give it to them, Frodo? Do not be too eager to deal out death in judgment. Even the very wise cannot see all ends. My heart tells me that Gollum has some part to play yet, for good or ill before this is over. The pity of Bilbo may rule the fate of many.
In case you wanted some closure on the “who bought how many rings and when” issue from YOI ep 10, I think I’ve finally found the clearest, most explicit confirmation we could hope for:
It’s a statement by Toyonaga Toshiyuki (Yuuri’s VA), in the January 2017 issue of Animage (scans by chaotic-tendenci). It’s an interview, the question being “What was the most memorable scene from episode 10 for you?”
Toyonaga: “[…] What surprised me most was the scene where Yuuri bought pair rings for Victor.”
Yuuri bought both rings.
(Feel free to check my translation but the word ‘pair rings’ and the wording that Yuuri was the one to buy them makes it pretty clear.)
*draped over a plush, black velvet armchair with gold trim, wearing a floor length blue gown in the middle of the day, holding a hand with many large rings delicately to my chest and sipping soda from a wine glass* what ever do you mean?
Look here, Sam, dear lad,“ said Frodo: "I am tired, weary, I haven’t a hope left. But I have to go on trying to get to the Mountain, as long as I can move. The Ring is enough. This extra weight is killing me. It must go. But don’t think I’m ungrateful. I hate to think of the foul work you must have had among the bodies to it for me.”
The Return of The King, The Land of Shadow, p.1201
In which Frodo shows his priorities once more - he’s almost overcome by the ring, the most corruptive power in Middle Earth, but he still makes it a point to be polite and kind, and considerate of Sam’s feelings.
