haha, i see what you did there. and to be completely honest jack would probably go somehwere around the lines of "OH GOD JOÉL YOU'RE SO CUTE SOMETIMES!" and joél would get all "i don't like you anymore." and then jack would calm down and say with a little smile "well, that wouldn't change the fact that you're one of the cutest thing i've ever seen." and then he would wink at him while grinning. and then joél would get really angry. oh gosh. i wouldn't want to be jack then. um. you probably didn't want to hear all this. but... those are just the in-character reactions i wanted to share with you for some reason. hope you're not mad.
haha, well they're kind of similar. even though joél is not as grumpy as romano. and jack's not as oblivious as spain... at least most of the time. when i actually discovered hetalia i thought jack would be some kind of spain-america-france mix and joél a mix between england and spain (because joél is way too oblivious sometimes.).
