i finished nightmare 3 i have a few questions

1 how did the mad prince have akanes mantle if that version of events technically never happened.

2 why did the sin of solace protect sunny from the mad princes rambling or whatever secret he was going to tell him.

3 how did he even enter his dream was it a remainder of the mad princes will hidden inside of him or something.

4 how did the sin of solace exactly grow to become like sunny 1 to 1 appearance wise was it always a part of its abilities to become more like the wielder just so it can ragebait them easier.

Yeah thats all if some of these have spoilers just say spoilers and i want ask for an answer thanks.
