Thanks, James. So I think I think on a capacity standpoint, there's obviously there's a lot of time between now and 22 and 23. I'm certainly I think our current expectations is that our fleet will be back up and running certainly by 2022 and 2023. Capacity for us is likely to be higher, because of the new ships that I talked about in my remarks coming online. But at the same time, as I commented, on Steve’s question, we do continue to opportunistically look at ship sails or scrapping and very kind of remote type of situations, which could lower that capacity growth number down a little bit. But I would expect our capacity as we look in 22, and 23, to be higher than it was in 2019. Driven by new capacity, we've already taken out some capacity, the scrapping of some ships. And of course, as we know, as the ships roll on, the higher inventory mix more onboard revenue venues, the more cost much more fuel efficient lead to really enhancing our margins. Moving on to leverage, it is certainly a goal of ours, to get back to our pre COVID level metrics, especially as it looks like we are getting to investment grade, I think how we look to do that is obviously putting more of our free cash flow towards paying down debt. We've taken some action here recently, to put ourselves in a position to pay down debt. And hopefully, the sooner we get started here, the less of the cash that we're holding, today, we're going to need and that can be purpose to also, paying down debt. But it is it is definitely one of our management team on our boards kind of core objective to look at, how do we get to pre COVID leverage, as soon as possible. I won't really comment on its just way too early to talk about consensus. For 2022, I think important variables will be when we get the green light to get back into service, and what that ramp up looks like, what the universe looks like around therapeutics and vaccines and testing. And of course, your wave is very important to 2021. But waves also begin the momentum into 2022. And so, the more for us, the flywheel is spinning. As we go into all of that, the more momentum I think we'll build for 2022. So we're cautiously optimistic, I won't talk about whether it will be a pre COVID levels by 22 or 2023 except to say that, we're trying to build momentum as quickly as we can and making sure we're doing it in a very safe and healthy way.
