Alex, Carina, DeLuca, Richard, Bailey and Teddy were all Arizona's people! So many opportunities to mention her, especially with a geriatric pregnant Teddy, Alex (Arizona's mentee) as interim chief and all the baby-in-a-bag stuff.
What's funny is that that's exactly what Ellis did with Maggie/Richard, and Maggie knows that, and she knows Richard, but instead of building a relationship with him, she's dating his stepson. I wonder how Jo feels about that lol.
Jolex will probably adopt it.
