"Tony, I keep telling you to not get hurt." Jon points out with a bewildered look on his face. Since it's true. If there's one thing Jon keeps telling Tony, then it's to be careful. But he doubts that's why Tony has put him into this armor. On the other hand him being in the armor means that Tony isn't. And maybe it means that Tony is less likely to get into any dangerous situations.

Jon sighs once, then nods. "Fine." He can try. If only to keep Tony safe.
