She didn't really have answers to any of that, but she didn't think the idea of stars seeming impatient sounded whack. When Lyra was impatient (not infrequently; the world didn't move quite the same pace she wanted it to) everything else seemed impatient too. You pushed your own feelings onto things, that's what dumb mammal brains did, right?
"Iunno," Lyra said, trying to answer anyway. "S'like luck I guess? Sometimes it's there and sometimes it ain't and no telling till it's over. Oh— Merlin! That's why the trip to Merlin?"
When Rosario had first sent that message, cool as you like, Clio's introducing me to Merlin this afternoon Lyra’s first thought (and she wasn't proud) had been a stab of FOMO— without me?! Rosario knew how fascinated she was in Merlin, why was she going to meet up with him without her? And on New Year's Day, of all days? Couldn’t Rosario wait like, a few more days till Lyra was back?
Any remaining tang of jealousy subsided pretty quick when she answered her own question— no, Rosario couldn’t wait, cuz if she could have, she would have. And this was why: seeing Merlin and getting his answers was so urgent it had to be done then. That realisation had Lyra feeling both stupid and selfish for being jealous, cuz it wasn't like Rosario was going for a laugh (even if they had been meeting at a comedy club.) Nah, it was all about self-discovery, wasn’t it? Untangling the giant tangle of question marks Apollo had dumped on her with his stupid genetics. Rosario had been, Lyra'd realised, doing the exact same thing she had been doing in Vegas. Poking at the edges of her known self.
So yeah, no, legit, Lyra had no right to ask Rosario to hold back from that mission on her account (even if she did really want see this not-Gandalf beard with her own eyes.)
