You would have to be more specific with what is bothering you about it. Simply posting some pictures won't help.
The 'new' repeater isn't a repeater its a comparator. I think this link will work he is a guy I watch its a video on comparators.
i need help not with the comparator but with the pic that has 3 repeaters on it and the one in the middle is like bedrock
It's a repeater lock I'm on my iPad now I can't upload a video all I can suggest is to search 'repeater lock' on the web.
Ah, that is known as a Latch, and it is a way of locking repeaters into there current state by powering them from the side.
Basically, when you power a repeater from the side, a "line" appears in it, which locks the repeater into whatever state it's in. For example, if you power a repeater from the side, it will remain un-powered, no matter what.
