Akito is already pretty open with all the things, but he might have a habit of saying things he normally holds back, so he might be a bit blunt with people. Also people he likes will be getting hugs and sudden random, glomps. Tsuna come here and let him cling to you
Agito...is much more likely to actually attack when his filter goes, so he miiiight be unaffected by this. Just so he doesn't try to kill anyone.
Lind will be much more honest about things, because he has a very heavy filter that will be disappearing. Anybody want to play with him? He'll also be asking a lot more questions and be more Gaze-like in general.
