Annelise and Philip in "The Americans"

How realistic do you think it would be that she never tried asking her "Swedish" handler to talk to her in Swedish? I don't know how well-trained P&E were in any languages besides English, but if Philip is going to pretend to be a Swede, he should at least have a basic working knowledge of the language, no?

For someone like her, I can easily imagine her teasingly asking Philip, "How do you say 'I love you' in Swedish?"

For him to hem and haw at that point could've raised her suspicions, but I can't imagine him knowing enough to toss off a "jag älskar dig" and give it the right pronunciation so on the off chance she met a real Swede she wouldn't wonder why Philip spoke actually rather crappy Swedish.

Or maybe it just never came up?
