Obviously there's been a lot of chatter on the ending of the Penguin. I haven't seen anyone mention, however, how in the final scene of the series, Eve Karlo is disguised as another person entirely. Karlo, as in Clayface.
I cannot help but feel that having Eve Karlo looking exactly like the Penguin's mother goes beyond being a huge nod to Clayface. It's basically an adaptation within the bounds of this universe.
