I don't think so. She probably has intellectus for all matters related to death, so in a sense she's there, but no need to come in person. Arthropos (one of her name), did her job with her shears without leaving her home.

This may be true, but MW losing her walking stick may also be used as an explanation of why humans are living longer lives now than when she had it. Also, The 'our' used by MS to describe both her and MW to me makes complete sense. In all of mythology Death has been described as a distinct persona but closely connecting to its counterpart - whichever word was used to describe Life. Death defines Life and Life enables death. One is not the same or complete without the other. That also brings up an interesting theory I have been thinking about - are the Mother mantles connected in a symbiotic way? Do the fae mantles get farther apart in purpose with less power?

MS is obviously aware of the purpose of Winter and helping the knight of Winter, while the Summer Lady and Winter Lady are the weakest, most prone to wanting conflict between the courts and most vulnerable to outside influence as is proven with the corruption of 2 Lady's and the death of 3. Titania and Mab are obviously not on friendly terms but seem to, at least for now, not be as susceptible to outside influence and want to keep the peace to focus on important matters like the Outsiders and the Outer Gates. So are MS and MW actually 2 faces of the same mantle, god or whatever you want to call it since they appear to be aligned in purpose and actually appear to somewhat like or need each other? What names from mythology take Death and Life into account as well as the seasons?
