I couldn't find a scene that exactly matches in words the lovely painted pottery. Before re-uniting, both Electra and Orestes, separately, begin long speeches with a call to Hermes. Then, when together at Agamemnon's altar, they share a duet of profoundly moving lyrics. But Electra lost in thought? That's a liberty.
CHORUS:
Where will it end?--
where will it sink to sleep and rest,
this murderous hate, this Fury?
This is Hamlet's strong precursor, innit?
