Must save Natsu!

A panel from Fairy Tail Chapter 514 where Lucy and Happy try to save Natsu from certain death, using the warm generated by their body to maintain a rightful temperature in Natsu's body; in other words, that's another pretext for Mashima-sensei to show us Lucy and Natsu liying in a bed, nude and very next to each other.
What's you opinion about this chapter? In particular this scene?
I'll submit something about Eileen in the following days.
Thanks for the appreciation.
