read this in a chinese forum
i translated to english here coz i was there in the con that day and witnessed this!

when sho's blade was not coming out in time, i bet all the 5 guys were as anxious as i was LOL... but aiba, jun and ohno sort of went on dancing as if nothing's amiss, and sho's face was all black and he was sort of hesistating about what to do next ><, then suddenly nino, left his own spot in the formation and passed his blade to sho. then picked up the blade that came late from the ground.
at that point, i really kowtow to nino myself ORZ!!
he's really thoughtful and smart. and i was thinking, he must be damn cool and calm during the performance to be this clear-headed O.o

anyway, here's the translation:

the theme is called 'join'
about one another's working relationship etc...

"regarding 'interaction', i think about work, especially with the members.
if i was stuck with another job and couldn't attend the rehearsals for the con, the other members would video it for me.
or if someone else was occupied with other jobs in the morning, the others would help to cover his part for him.
although it's mostly small things, like after the osaka dome con in spring, in order to have an even better performance in tokyo dome, we would gather to discuss after the performance.
at the time, the other 4 guys had other jobs, so i was the middle man/coordinator between them.
it's not 'hey, let me do your job for you', more like depending on the different situations, whoever's most flexible at that moment, could help out abit.
it's really fantastic that we could help one another out this way.
as we exist as a team, thus there are many occasions where we have to help one another out.
like during our talk, who is more high, and who is more cool... we've got pretty good chemistry for this.

this reminds me of the kaisen con in january.
during the 'right back to you' where we were all dressed in warrior outfits, my sword didn't come out.
if i had to wait for the sword to appear, my dance sequence wouldn't be able to catch up with the others.
just as i was hesitating whether to do air-warrior-dance, nino, who was behind me, suddenly gave me his sword, then he took the sword that appeared later instead. so the whole dance sequence went on smoothly.
i didn't expect to have such perfect partnership!
that time, my heart sort of knotted up and i nearly fell in love with nino (laughs)."
