i know it's her way of encouraging her little sister but man oh man

in the anime they didn't cut out much overall, but it would've been nice if they'd kept the full fight between Fubuki and Super S/Do-S; i feel it helps showcase her abilities as well as further touching on how she is in fact stunting her own growth. she herself already acknowledges she's powerful enough to advance through Class A, and it's later depicted that she's definitely capable of progressing her abilities, even just by properly utilizing them to begin with but instead she maintains a stranglehold on Class B Rank 1. which again not only stunts herself, but likewise hinders the growth of her followers by keeping them in the same positions both in Class and in fealty. . Tatsumaki isn't fully wrong that Fubuki's maintaining of the Blizzard Group is holding her back, however she is NOT correct in that having others around you is the source of the hinderance. having cooperating allies is a good thing the benefit to such teamwork is also demonstrated later on the problem lies in the fact Fubuki maintains a hierarchy of idolizing followers to satisfy her inferiority complex rather than treating them - or even seeing them - as true allies, and potentially friends. connections she herself yearns for just based on her initial interactions with Saitama. . it doesn't help that Tatsumaki also stunts Fubuki just by being so overprotective and austere in her equally traumatized way of mishandling social interactions. she infantilizes Fubuki, keeping her from growing and then furthering her inferiority complex by putting her down, belittling and insulting her efforts under a frequent taunt of sticking to Class B along with her group being a burden. she's both right and wrong, and unfortunately her approach to what she IS (somewhat) right about is gone about in a wrong way, making it...well...less right. . really these two are just a mess XP

Not them spelling out a word. At least her big sister loves her even though she is rough around the edges.
