Michael had expected to return to a orderly, perfect, polished skies of the heaven only to see residue of a powerful shield and the heavenly gates shattered, with whatever blast shot from what it seems to be.. hell had pierced THROUGH the entirety to heaven...well not as in heaven was demolished but there's now a huge gap.

"What in fathers name happened... "

He muttered confused, flying through heaven and inspecting the damage

[Which was what hes doing till his called by the current seraph watching over hell and was told to 'check' on Lucifer.. Not 'fight'. Check. HE WAS NOT GIVEN CONTEXT WHAT HAPPENED EVEN]

all he could do was nod in respect not wanting to question his mission... He'd just ask his so called brother what HAPPENED and WHY?!

Gosh if this was Lucifer's fault again he swore he will-
