It's a good thing Madoka is so oblivious. The fact that Prompto just nearly misunderstood what she was talking about goes about fifteen miles over her head. Instead she just smiles at his words as he agrees with her. That sounds like Prompto the way she's gotten to know him. He always tries so hard to be sweet!

Although it doesn't seem to fully help Maru, which is worrying. Madoka is totally fussing over the other here, which probably looks ridiculous since Maru definitely is the taller and older-looking one here. But Madoka looks up at him with a tiny, but very serious-looking worrying frown, making sure to keep holding the other to hopefully provide him some comfort.

"Hmm, Maru doesn't drink blood to live." And honestly, even if he did, Madoka wouldn't judge him. It's like Prompto said, people should get the help they need. But since Maru seems to be trying to explain this to Prompto, Madoka figures she can help out as the one with more energy here. "He can eat just like us! He really likes snacks. Like chips."

She gives Prompto a small smile at that, despite the hints of worry left in her face, to try and make things a bit lighter.
