I liked all them instantaneously....even Magna with her defensive stance in the beginning.

 

Yes, Magna's a fun character. Yumiko though needs fleshing out a bit, imo.

 

I do not read the comics (I did but quit prior to Magna and Co arriving)...but it seems that Magna was the "leader" of their group in the comic. On the TV series it seems that there is more of a democracy among the 5 of them with Yumiko oftentimes (not always *cough* season 9 go rushing into the woods at night) the voice of reason, calmness. Actually Yumiko, Luke and Connie seem to be the more level headed with Magna and Kelly more likely to react before thinking.

My point being that with no real leader at Hilltop currently I am thinking that Yumiko would be a great choice

 

Isn't that how one "silence the whispers"? By signing
