Theo didn't miss the glance Ron gave Harry, his brows jumped to his hairline when he took in Hermione’s graceful form, smothered head to toe in the enemy's blood. One would assume that after her first kill she would disintegrate into a thousand different pieces and they would be required to put her back together. Theo drew his own strength from her unflinching form as she performed the required spells. They had a job to do and they would burn the entire population to cinders if it meant being one step closer to their bonds. They were not only fighting for a better world, they were fighting for their own survival in all of this. For insanity was not a route Theo would willingly take. If Luna perished, he would soon follow. Harry’s bond was safe, he did not have the constant fear of their impending death looming ever present over his shoulders. Although not free of the pain completely, at the very least he did not have to worry about whether Ginny was alive - his biggest worry was when he would be able to see her again.
