Do either Agnes or Caine pick up on Tagalog from Pauline?
They don't really usually hear Pauline full-on speaking in tagalog because there's no one else who could understand what she's saying (aside from their more intimate moments, where Pauline teaches them new tagalog words of endearment)...
... but there is the occasional casual swearing slip up, to which they would immediately ask what it means out of curiosity.
Of course, Zach (Jax) already knows a handful of the swears and insult in tagalog because Pauline (Pomni) calls him those casually, ESPECIALLY when he's up to no good.
