Mjoll the Lioness is a two-handed warrior, but her favorite sword, Grimsever, is a one-handed glass sword. Rather than change Mjoll into a one-handed warrior (her combat style and perks show she was definitely intended to be two-handed), Grimsever is now a two-handed sword.
I also always thought that Mjoll the Lioness should have the two-handed sword. But today I made a grim discovery. When you are on the quest to retrieve Grimsever and find it on the bloody table (where Mjoll was hurt and disarmed by the Centurion) you can find a shield right next to the sword. Of course a shield can only be used with a one-handed weapon. I looked and there are no corpses, other equipment or other blood splatter around, so the shield was also used by Mjoll. No other adventurer probably entered this far into the ruin ever.
Of course Mjoll has perks for two-handed weapons and wields one. Maybe this is actually storytelling by Bethesda and Mjoll trained in two-handed after loosing her sword, so she could hold her weapon with two hands and not be easily disarmed again (plus a two-handed weapon looks more imposing to the thieves of Riften).
If it isn't and Bethesda just messed up, maybe Mjoll should actually have one-handed and blocking perks (or maybe both one-handed and two-handed perks). Or maybe the shield should be disabled? Or everything should be left as is? Definetly not marking this as a bug report since it seems like Bethesda sometimes just loves to make things inconsistent for no reason.
Would love to hear the thoughts of the USSEP team on this.
