The "Atlas Pillar" moniker seems to have caught on, as evidenced by the fact CONNIE uses it and, hey, it's her house. She can call it whatever she wants.
The old, used pillars Connie obtained don't quite match the one remaining pillar, however....
Connie has a quirky, creative idea about leaving the "Atlas" pillar in place, and actually painting the "reinforcement" pillars in such a way as to emphasize the fact they are different than the original remaining pillar.
Hey, it's HER HOUSE. She can do whatever she wants, within the law.
And, really, isn't that the wonder of home ownership? NoMi is the place where you can fix, flip, renovate, restore, and express all that "This Old House" creativity just dammed up in your soul, all at an incredible bargain.
