Yeah, so as far as the increase in intraocular inflammation, there's no doubt that there was a spike. To the best that we could do looking at every variable, it seemed to trace to several batches of syringes. But, of course, in the absence of doing a controlled trial, one can't be certain. But what we can say is that the background rate typically is about one to two cases of inflammations per 10,000 injections. The marketplace notices when you get to 5 per 10,000 or 10 per 10,000, they notice it quite a lot. And I can tell you that we spiked up above the one to two, and we don't think we quite got to 10. But we certainly are now back to the baseline of one to two, and we monitor this very carefully. Not to break our arms patting ourselves on the back. I think that we handled that very transparently with all the various retinal associations and ophthalmologic groups. We shared the data directly with the key opinion leaders and anybody who wanted to see it. Marion's team was out there. We got lots of positive feedback. I'm sure we lost some customers during that, but I think that we're winning them back, because of our transparency and the fact that we've got the rate down. Now, in terms of new agents, yes, inflammation could be a differentiating factor. I think I've seen rates in some of the newer types of agents that are up to 15 per 100, 150 per 1,000, 1,500 per 10,000. Remember, we're talking about in the outside – in the world as we monitor, we're looking at rates of one to two per 10,000. So, yes, if those rates don't come down dramatically, I don't think that we would be overly concerned about the competitive nature. I just want to say that, to emphasize that, we look very carefully at the competition. We don't see anything coming along that is going to be highly differentiated from the data we've seen from our molecule. And remember, we have recently gotten, as George highlighted, an approval in Europe based on a study that the FDA hasn't seen yet, but the ALTAIR study, where we got a label that allowed for extension of dosing, through a treat and extend dosing regimen in the first year, where 57% of the people were able to get at the end of a year to an intended regimen of 12 weeks or more, and still gaining an average of about 9 letters and many patients achieving an interval of four months. So I think EYLEA has incredible profile and we don't see anything coming along that disrupts that profile. And we certainly don't see anything that can have the broad number of indications for a very long time that we have in our emphasis on diabetes.
