That girl isn't very subtle. If she wants to manipulate someone else than a specially gullible kid, she'll have to learn to do it without an evil grin.
But she got the spirit right. Trust the minion to work, and continue with your own business while stressing over it wouldn't help the outcome. With more experience, she'll be a dangerous one.
I suspect that had she been subtle, he wouldn't have understood enough to be manipulated...
Wait, gullible doesn't always mean stupid!
Though it's a hint in that direction.
That blanket or maybe tapestry in the background in panel 5, is that showing Orcs shooting down a plane with spears? (Made me smile thinking it does)
Yes it does!
Whether it actually happened is another question, but that's what's drawn!
