Did you even watch the episode? Deino came out of the bush days before the trainer returned, after that it was getting close to iris. And I highly disagree about it being unemotional. The moment Deino was recalled back into its pokeball, you could see the story on Iris's face. She had grown attached to it and didn't want it to leave her.
Im just gonna start by saying i really dislike your tone, you did this in the other thread, almost as if your trying to make a flame war or something.
Anyway, yes i did watch the episode. It came out the second night to eat. The third following day it came out but only to Iris. The next day it remained out until the afternoon when the trainer finally returned. Basically, you saying it came out 'days' before the trainer returned isn't true, it only came out of the bush properly for one day and a half. Two days if you count the evening where it started eating.
And about the second half, that's your opinion, i didn't find it emotional enough, and i don't think it would be overly emotional for a child either. She may have bonded and become attatched with it, but it's clear that once Deino's trainer returned she was pleased for it when it was with it's trainer again, she showed a split 2 seconds of emotion (don't believe me? look at the images or watch the episode again) in her eyes, but immediately after smiled and waved goodbye, she was happy that Deino was happy.
It wasn't very emotional for me, since i don't think she bonded with it enough.
Cilan said "didn't you want to say goodbye iris?",
Yes, i've stated this.
meaning she could've asked the trainer for a moment with Deino, but realized that seeing Deino's happiness was all she needed. This made it even more emotional, but you clearly missed that.
Your right she could have, but to me my first immediate thoughts were 'what is she doing? is she too shy to ask the trainer?', and then the trainer left. I never thought about the emotional side of it since personally i don't think it was done properly, i didn't feel she bonded enough with it, and each day rushed by way too fast. That's the disadvantage of the show being 20 minutes.
