In the End Phase, does Brain Control return the monster before or after Book of Eclipse flips monsters face-up?!
You used Brain Control earlier in the turn and Book of Eclipse was activated. Both have End Phase resolutions.
End Phase effects resolve in priority order starting with the turn player. The turn player chooses whether to resolve Brain Control first or pass priority; after that, the opponent can resolve Book of Eclipse. Mandatory End Phase effects must resolve before the phase can end.
Does the flip-up portion of Book of Eclipse start a chain?!
Book of Eclipse has resolved and you are checking whether the end phase flip-up is a chain effect.
No. The flip-up in the End Phase does not start a chain.
