Lyla agreed with Sean and she continued talking
"You are very good with the use of a dagger. Are you sure you want to do this? Are you sure you are strong enough?"
Sean understands Lyla is asking if he is mentally prepared for the fight against the devils and he won't just get killed before the fight starts.
"Come on, I made this decision and I'm ready. Moreso, I've got no choice, unless I want to be trailed by devils until I die or the tribulation is over. If I'm lucky, I have to do this. Sean smiled and reassured Lyla.
He didn't want to risk their plan.
He had not minded fighting the devil soldiers. If it was some human soldiers or thugs, he can easily dodge them instead of going to a fight with them. But this? With the scent?
It surely was a different matter entirely.
