Noooo, it was LATIAS, OBVIOUSLY, 'cause Latias can't speak while in her human form, and she didn''t say ONE word to Ash, even to give him the drawing. if it WAS Bianca, she would've said "here, this is for you" or something like that. BUT LATIAS said nothing, 'cause she COULDN'T. so THERE. ANYWAY, it's much cuter thinking Latias had a crush on Ash just like his Chikorita/Bayleef,don't you think?
i still, and always will, believe it to be Latias. after all, if it WAS Bianca, WHY didn't she SAY anything, huh? she could have said "This is for you, Ash." or something like that. But instead she just MIMED the words, so Ash understood her. That PROVES it was Latias.
ikr? Its was soooo cute! Pokemon are obsessed with ash seriously chikorita and now a latias who kissed him (chikorita kissed ash too! LOL! it should've came out of it pokeball and battled "bianca" It be hilarrious!
