So, with respect to the other members in this forum, I thought we'd not ruin everything in that thread and instead clear up a few things here.
I'm not justifying Eclair's behaviour as true and just, it's without a doubt she's been rude to him since the battle and she's not helping his situation, although it cannot be overlooked that she has her own reason for acting the way she did, though not deserving of the title "bitch" (which in my opinion I'd reserve to a woman who'd have stolen my money) In fact, no one's helping his situation anytime soon, so there really was no reason to continue brooding over that fact, and there's no point in trying to despair over that fact, and with regards to absolutely no way of knowing when the next battle was going to happen, he really had no right to potentially ruin everyone's expectations of him after all the flair and hubbub of his flashy victory, regardless if he knew he could go home or not, considering the flashy acrobatics he pulled off several times to start episode 01, which for all intent and purposes is to show us what he really wanted to do, alien world or not: and that is... athletics. It was his choice to fight, and if he can't even get home, there's no point in regretting it now, especially after seeing the sudden kidnapping of Millimeter, anything can happen at any time, heck he could have been kidnapped making his world a whole lot worse. At least he had company, huh?
By the way, just thought I'd let you know that I have a habit of nicknaming characters, as I've watched so much anime over the decades, I like to depend largely on memory for remembering characters, and thus is the reason for why I name them the way I do
