It's a test for herself; whereas before whenever Mel wanted to Summon a specific spirit, she needed an item of theirs. But considering how she very nearly feels drunk off the power ghosting through her veins, the Goddess has confidence she can bring back anyone by focusing on the emotion behind the name. Or, in Damien's case, the name itself. If it doesn't work, she'll try for description instead, however touching him may be enough of a catalyst.

Trusting the hacker to temporarily guide her, Melinoë closes her eyes long enough to focus on Snoopy the feline. . .and ta da! Have your cat named after the Peanuts beagle, Damien. He's blocking their path and gives a mew in greeting, whereupon hearing the sound, she herself giggles out of merriment.
