lakooki theory time!
notice how she tapped her forehead when she activated teh sharingan??? it almost seems like teh forehead tap triggers teh sharingan's activation. There has been a lot of theories that Sarada will awaken her MS thru love and not hate or sadness and Kishi drew some art of Sarada with a sun-patterned MS
teh sun iz a symbol of warmth and positivity. Sarada iz loved by both her parents and they have expressed this through forehead pokes
Teh forehead poke iz a symbol of her parents overwhelming love for Sarada, feelings which resonate with her and make her stronger. This will eventually lead to teh sun MS! Which will be unique because teh light of teh sun will never fade from her eyes! We all know through Itachi's poke he transferred techs to sasuke
so it iz possible thet Sakura and Sasuke have transferred some chakras to Sarada with their respectives pokes. Byakugou chakras(this will regenerate eye problems)+Sharrinnegan chakras+overwhelming love=OP SUN MS! thx 4 reading!
