No, everything i mentioned has been shown or mentioned, and no i didn't jump the gun, you can claim i did if you want though i really don't care.
Sigh i guess i'll explain it as simply as possible.
I am mad that he hesitated to tell his master that her friend had been kidnapped thus delaying possible rescue measures (not to mention breaking his own oath as a servant), if he did it because he was worried she'd go after her he'd have a excuse, but as i said at the end of the chapter it's pretty obvious that he still did nothing to prevent that so his actions are both paradoxical and foolish and in a more strict society would be classified as insubordination in the first case endangering his charge in the second.
Look i don't care if you don't agree with me, i don't care if you got a problem with what i said, but at least don't make up me saying something i didn't.
Ok let me take this slow for you, we have not been shown that he let her go there, we do not know he took her there. Everything your saying hinges on the discrepancy of him shielding her earlier and the future knowledge that he takes her there. This is why you jumped the gun and spoiled what is happening. Right now what we have seen so far he has done everything exactly right. He noticed and rather than raise noise and escalate or let his charge give chase or be endangered he monitored ready to take action if they directed attention at them, once clear of the scene and safe he told her, went to the proper authorities and reported it rather than start a international incident, her request to go to Cain was perfectly safe and so he abided. He 100% did what he should have.
Now yes we see she is doing somthing at the end, we don't know details, we don't know how, we don't even know if its her at their hideout, its implied sure, but we do not know, and we sure as hell don't know who she is with or if he let her or took her with. Your grievance is entirely based on this, as such your a throwing a fit about events we havent gotten to. You clearly hated this and wanted to vent, and were waiting on saying stuff till it happened, but your line for it is messed up by hindsight, you already know what is happening so hints seem like reveals to you.
The worst part is, no one is agreeing with you, not because your wrong, if its as you say many would have agreed myself included, but you failed to wait and instead have spoiled things, so now everyone doesnt like what your saying nor want to back you. We also have nothing to go on to know if your right, right now at this point in the story your entirely baseless and just wrong, that may change later, but you decided to talk about it now, not later when it would make sense. So yes you jumped the gun, or your just baseless, we dont yet know.
