1. Simon pulled out an extra piece of attire for the attack on the Hilltop.
You may have been too caught up in the massive fight to notice its significance.
Simon whips out a jacket that looks quite similar to Negan's.
We've seen Simon wear the jacket before, like on the season seven finale seen above, but it seems even more important Simon's wearing it now with Negan missing. Simon has assumed leadership of the Saviors with Negan missing in action. What better way to take over Negan's role than by looking the part?
Bad news for Simon is that Negan's alive. When he returns, it won't be good news for him.
2. It's not just Negan's clothing that Simon's mirroring.
When the Saviors reach the Hilltop gates, Simon delivers a familiar line of dialogue while throwing some shade to Negan.
"Well, here I was hoping to give that gate a big old wet, sloppy kiss and there she goes playing hard to get," Simon says after Maggie's spike strip in the road derails his plans to crash through the Hilltop gate.
Simon's mocking a line from Negan's last speech to the Saviors.
Right before they left for the Hilltop, Negan encouraged the Saviors to make sure their weapons were covered in walker entrails. That way they don't need to kill anyone. They just need to cut them up with the tainted weapons.
"You see how Lucille is getting to know our beautiful, cold friend here? That's it. Look at that. No more smashing and bashing with this. With this, it could just be a touch or a big, wet kiss," Negan told the Saviors to get them excited. "Either way, this gets you full membership and that's what we want. We want people to join the club."
Simon thought that was a bad plan and told the Saviors to kill on sight.
3. A man gets cut up pretty bad from a Savior and Carol immediately runs to his aid.
If you were confused by Carol's soft spot for the injured man, it's because the two had a brief fling. You may not recognize him with all the facial hair.
This was Carol's extremely short-term love interest, Tobin, from season six.
The two shared a porch cigarette and then Tobin thought they were an item. Carol broke his heart and ghosted him when she vanished off to the Kingdom an episode later.
Tobin's been lurking around Alexandria as a background character ever since.
