I think Belle Vs. Stella, is a good comparison....
both have the super power of talking/chatting....both struggle to gel with the girls...stella coz she is stella and belle is considered too young by all...\
But their attitude is absolutely different....Belle roams from place to place...stays in her own world...sometimes dancing, sometimes joking, sometimes on phone..she doesnt seem too bothered and under pressure to perform...and she doesnt really interfere...
When Stella is isolated...she sits in the corner...checks her phone...fine till then..but then she starts feeling pressure...she keeps on staring, and then when she realizes that a few girls are missing ...she figures out..they must be in balcony or rooms and if they are there ...they must be talking..thats the only thing that makes her comfortable...so she goes around searching and then interferes badly in between any intimate moment that could happen...talking is her only solution to pass time...
