Well, in the case of Penlod, I would think that he's a significant character to cast since a) he's Pengolodh's father, and b) Aredhel knows him well enough to trust him with her command. For Bregolas, I thought there was a niche slot for one of @Nicholas Palazzo's dissolute youths of Nargothrond and he'd be a mentor for Barahir, which Professor Olsen mentioned in one of the sessions for the family trees.I understand! But a couple of them are just postponed, I believe. At least I think Galdor should probably be cast next season. And there's no reason to rule out casting Penlod at some point.
