Although Archer's actions were stupid and insane, they were stupid enough to get his father's attention. The grunts in the room are full of uncertain feelings about this heir that suddenly showed up. He doesn't need to make a worse impression.
He forces himself to settle down. At the same time, he should... at least try to exert some of that control he supposedly has.] I want you to promise me that you won't try something that stupid. [...He can't just say stupid. He has to make it sound like more than that.] Stupid, reckless, and ineffective. [That's a little better, isn't it? ...It sits even worse with him.]
