I tried skipping through the episode but I watched the safe house bits but I can't find the bit where he's actually looking at the icicles :(

I think the whole "I hide what I do not who I am" thing coupled with the "youve lost your humanity" car speech as well as the fact that the Mossad agent gets to regularly go back to his homeland, makes Philip sad. During that conversation, I was thinking back to last week's discussion about how the illegals in real life were dragged back for polygraphs but in the show's canon, they'll likely never see it again. The Russia they're fighting for exists only in their memories and their beliefs, and feeling those memories fade must be really sad and helpless and unrooted.

I think this was just my mind leading me off to places but when the Mossad agent said that he wanted to be buried at the Mediterranean but we can't all have what we want and Philip says "Nothing's easy" I just thought how sad it was that if things do go well for them, they'll never see their homeland again, will be buried far away from the place they dedicated their lives to.

I love what you're saying about Elizabeth rooting him, just with her presence, the only other person who truly understands and who is real to him, despite all the unknowns between them.

he's been being other people for so long that sometimes he's not sure he could still be himself."
I like this a lot!

I really liked this bit from Todd's review too
Henry and Paige are forming those sorts of nostalgic ties not to the homeland of their parents, but to the country they were born into. For as much as Elizabeth and Philip might hope that, deep down, their children would be loyal to them, a homeland is difficult to ignore.
