just finished watching this for the first time - blown away!
quick question - does anyone have any theories on why she chose the russian woman over the nice middle aged, experienced foster carers?

Rena's poison wasn't hidden by beauty - it was out in the open.
White Oleanders are deceptive because of their beauty, much like Ingrid, Starr, and even Claire, whom Claire was able to further poison by giving her a push.
Ultimately, with Rena, Astrid saw it coming.
(Rena is the opposite of a white oleander; dark and outwardly rough. Ingrid, Starr, and Claire all represent the same light in their looks as a white oleander)
There are other nuances, as well, but this is the underlying current.
