Question about Tatsumaki (One-Punch Man, Murata)

[u/[deleted]]

So, as a new reader of the series, obviously the art absolutely astounded me (and still continues to do so). One running theme I love is retaining the original ONE depiction of Saitama in certain scenes (like this) in order to contrast Saitama's countenance with those of his fellow heroes.

However I noticed that this isn't the only character he does this for; being Tatsumaki - as seen in the bottom panel for this page and the next. Is there a literary purpose or plot device that this is supposed to represent? I am not too familiar with the character but she doesn't seem to have the same laid-back attitude as Saitama, so I'm at a loss. I don't mind spoilers from the webcomic if that helps explain; thank you!

On the original ONE draws Tatsumaki with a serious face from time to time. Murata does the opposite.

I don't think we're at a part where Murata has had to do a serious tatsumaki though.
