I spotted it much later on the countless reposts on social media. I’m unsure whether he’s intentionally bringing it to her (and assuming that she’d be on the roof) or whether the shawl somehow ended with him and he’s been carrying it around since then.

But when I watched the scene, I was more focused on the phone conversation (and whether he’d hear in the phone that she’s 406, as in, hearing the own echo of his voice back)
