Hmmm it must be something different... perhaps just your perception.
Nebula is huge (will check later for actual size) and any transient on eta itself (sudden brightening) will take quite some time to propagate through the nebula.

EDIT:
OK, found it.. the homunculus is ~40 light-days in diameter.. so, for the transient to propagate through would take couple of weeks.. so the nebula brightening (but delayed compared with eta itself) is plausible.
