And in terms of Part D, I think, you know, I just highlight how pleased we are with the progress we made over the last quarter here, right, being at over 80% of lives covered a full year out from launch is remarkable, and that means we've got great coverage on commercial as well as Part d. Now, I think the way to think about this is, as we mentioned before, a lot of these changes kick in in 2025 we do see that those things take a little bit of time as the plans push this through, sort of their downstream clients. And I think that the other effect that you have, again, as I mentioned earlier, is the Q1 reset. So I think that this would be definitely an opening of that second half of the market, we were seeing Part D scripts come through prior right through letters of medical necessity, prior auth, etc. This will ease that process and I think over time, we'll access more volume. But I don't think it's like a light switch. I think it's a steady build over the first few quarters of 2025 particularly as people got it worked through their recess in Q1 the plan resets it, and those things and those dynamics affecting how quickly that ramps. But I do think throughout 2025 we'll be able to see that Part B volume really pick up over time. And then in terms of retreatment, again, I think it is really early to speak to this but in terms of the payer dynamic, we don't expect any pushback from the payers, because again, a lot of these are very spaced out. Obviously, in all of our contracting discussions with payers, we built that thought process in that there could be up to a couple of treatments a year for a patient, and it's still a great value for the payer, right? Even at two treatments per year, it's a tremendous value, and the effectiveness is proven and quite frankly, the great story here is that if a patient's getting retreated because the doctor thought they had a great response. So you're not treating patients that are not working. You're actually typically treating patients where you had a great response. So the effectiveness of proven the value is there. So we've worked that into our negotiations and discussions with payers.
