Who appears in front of Ekwefi as she waits tearfully outside Agbala's cave?

Okonkwo appears suddenly before dawn. He decides to wait with Ekwefi outside the Oracle's cave.

Subtly, Okonkwo could be considered to be waiting for both Ekwefi and Ezinma, as he might consider it unmanly to wait for Ezinma, but would consider it manly to support Ekwefi as she waited for their daughter.

Eventually both the priestess and Ezinma appear.
