As a shipping author, I think Lisanna's last words to Lucy were quite significant. Either she accepts that Natsu likes Lucy now, or she's just saying in not so many words that she considers her a rival. Of course, as a NatsuErza supporter, I can't really find it relevant except that Lisanna's moved on with her life. Come on, Bixanna moments! It's just a matter of time!!!
Please stop complaining about Pikachu losing to "weak" Pokemon at the start of each new region. Its power is drained at the start of each new region, and anyway, it's equally bad storytelling for Pikachu to plow through all of its opponents.
