Strange as it may be, things can also be to clean, and that means that the good guys that eliminate the bad ones are also being cleaned and whiped away. To sterile is not good either apparently. There are more and more warning about using anti bacterial soaps and whipes. I lot of that stuff is now ending up in our water supplies and being consumed, that is also a bad thing.
What matters though is that Ophelia is home again, I also think that it is great that she did think of that, looking out for yourself is the way to go. Learning on the job is part of that....LOL
