I knew I had a song for Shallan somewhere!!
LINKIN PARK- Numb
Key lyrics- "Can't you see that you're smothering me, holding too tightly, afraid to lose control?"- Shallan says pretty much this in regard to her farther trying so hard to hold his family together.
"I've become so numb, I can't feel you there"- Shallan becoming 'numb' over her a certain incident and forgetting and nearly killing Pattern.
"Become so tired, so much more aware"- Lightweavers don't speak oaths they speak truths about themselves. "I'm becoming this,"- Shallan has frequently gone along with something only to find out she actually gets too comfortable in the role (e.g. Jasnah's wardship where she went to steal a soulcaster and ended up falling in love with 'scholarship') this follows into
"all I want to do Is be more like me and be less like you"- This is pretty much Shallan's plot-line her growing (and in my opinion misplaced) self-confidence, learning to be her own person.
Less notably-
"Put under the pressure of walking in your shoes"- Shallan thinks she is the only person left who knows about the oncoming desolation, Jasnah's shoes are mighty big ones to fill indeed.
"every second I waste is more than I can take"- I might be twisting this one a bit but to me this fits perfectly into how Shallan refuses to acknowledge events that have happened to her. Her subconscious will not allow her to waste time on what has happened. Not the fact that her mother tried to kill her, nor Shallan's killing of her own mother as a child not even the killing the farther who destroyed himself to protect her. Later on she is even surprised to recall she killed Tyn. Shallan is not a Kaladin or a Dalinar who keeps their failures and fears close, she has seen from her family how that does not work. Living without her distractions would be "more than" she could "take".
Well I am glad I got that off my chest, seriously Shallan is such a well-written character.
