Who is this lady?

[L Verge]

Kudos and thanks much to Steve for digging this out! I couldn't find/access it! It's interesting that Holzer obviously turned "he went on stage during the masquerade scene" into a guest role. (Is "going on stage during the scene" necessarily an entire role?)

We used to call those walk-ons, and they required no lines or even motion. Wonder if Robert was in masquerade?
