Your sire doesn't like Sentinel? Well, that certainly wasn't in the plans for him. He expects everyone to treat him like a royalty and look up at him, so when someone treats him differently, it kinda catches off guard.

I don't think yandere!Sentinel will go into his 'killing mode' the moment he sees an obstacle, mainly because he's sure he can take care of that in a classy way.

Sentinel is definitely that guy who really wants to make a good first impression on your sire. He might act like a really confident mech in front of you, but for some reason, he is a little nervous about the thoughts of meeting your sire.

In his mind, it really goes quickly from «oh come on, why would her father dislike me? Everyone loves me!» to «oh Primus. what if he hates me?» and that's how it repeats 24/7. Eventually, the confident Sentinel wins, but he takes a lot of time to prepare for any possible scenario. Everything should be perfect, every single smallest detail is personally checked by him, so nothing goes past.

Imagine Sentinel's expression when your sire harshly brushes it off with a «You're not good enough for my daughter and I don't want you around her. End. Of. Story» and just SLAMS the door shut into his face the moment the other bot sees him. Basically, that's where everything goes wrong. Oh, his poor ego.

Yandere Sentinel especially hates when something goes wrong and not according to his plan. He's a perfectionist, and if he spots any imperfections, it's a total disaster for him! His mood quickly changes from sweet and kind to annoyed and impulsive, so it's better to stay away from him for a good few minutes until he takes a deep breath and goes like «this is fine...everything is fine! :)» with his optic twitching and a small frown on his faceplate, which is easily noticed through his smile.

Yandere!Sentinel gets paranoid with the thought that your sire will start putting the wrong thoughts in your processor, talking trash about him behind his back, so eventually you will start to question your love for Sentinel as well. So, he decides to step in and turn the tables, planting the seeds of distrust about your parental figure. Does your father really care that much for you? Nothing is wrong with being a little protective over your own little spark, but you're no sparkling, you should build your own life!

He does it carefully, using tiny, innocent and careful remarks whenever you two are alone after another disastrous meeting with your sire.

«If your sire really wants what is best for you, why he takes your chances of happiness?»

Until he practically struck you with a head-on, «You always tell me that you love me. So you should choose. Me or him.»

Sentinel is selfish. A small part of him understands how ridiculous it is, to feel jealousy just because your mentor is present in your life. But when you start having more of those father-and-daughter times together, when your attention goes more to your sire rather than him, all rationality in his processor just disappears.

He spends half the day trying to call for you. He wants to know where the frag you are and WHY you don't pick up his calls immediately, since he needs you right here and now. As his partner, you're obligated to always be there for him, and being ignored by you...the audacity!

Sentinel walks in circles in his office, and the silence is bothering him to the insanity. One moment, he will start crying his spark out to her about it.

“After everything I have done to her..! Can you imagine that?” he looks at Airachnid for validation, his voice full of frustration. “I swear, if she calls back, I'm going to tell her everything I think of her, that—”

But the moment he sees your name popping up on the screen, he is conflicted. On the one hand, he wants to pick up immediately, on the other hand, he doesn't want to seem desperate. So he waits a few seconds until he finally decides.

Airachnid gives him almost a disappointed look as she sees her boss using that sweet voice when he talks to you. Suddenly, Sentinel is not that angry anymore, and if anything, he's relieved to finally see and hear your precious voice. He almost forgets about what he said a moment ago until you hit him with «oh, sorry Sentinel, I was with my sire all day. I can't visit you today. See you tomorrow!».

He almost snaps the device in his servo by the end of the call.

Eventually, Sentinel gets exhausted from all of it. He really tried, despite the constant disrespect from your sire. He has no remorse when he finally asks Airachnid to deal with the obstacle in his way of getting you, covering the story as an incident. The death of your sire would shatter you, but don't worry, you will heal soon enough with him by your side.
