Yes. Yes it does. Like maybe none of that other stuff - the stuff they shoved back into our heads by way of 'update' - never actually happened at all. [Not Ianto's death, unfortunately, because that happened before he arrived, but the Miracle, and his own possibly final death, and those of others he'd cared about. A slow smile starts to spread over his face.]
I don't know how that would mesh with those of us who appear to come from different points along the same timeline, like me and Ianto, but it certainly does give hope, yeah!
