not hilarious or bizarre...but awesome moments with Lydia, yes.
Don't remember the location - doesn't matter - but the 2 of us were about to wipe-out a group of draugr.
I have my Lydia leveled up (I'm lvl31 myself), so she's quite capable of handling herself in combat.
I decided to let her do all the work, but conjured a (dual-casted) flame atronach to assist her, just in case....it would cause some distraction, so she could focus on 1 target at a time.
She wears a ring and circlet to enhance her stamina, and a neclace to boost her blocking-skills.
She's equipped with my 2nd Dawnbreaker, and hardly switches over to another weapon, so I guess she likes it

Anyway, I watched in amazement, as she began the slaughter, and the 1st draugrs started to explode (a random side-effect of the Dawnbreaker)...it really looked like this got her fired-up even more, because her next moves were so fast, that it was over before I knew it!
2 enemies were left, attacking her together.
She made a 360dgr spin around her axis, killed 1 enemy instantly, and the 2nd fell nearly dead to the ground.
Then she kneeled, changed her grip on the dawnbreaker, and killed the last draugr with a 2-handed powerstab in the chest.
Since then, I do this more often, sit back and enjoying the show

Sometimes, I use some ranged magic to manipulate the fight...but she's doing all the dirty work!
When things are going out of control, I step in for a brief moment, use the one or the other Shout, and Healing Hands on Lydia.
And the fight goes on.
question: to which level can she level-up (through console)?
level 35max?
