I wasn't sure but I thought it might have been the same Tequila.I think it's just become symbolic and they wanted to draw attention for those that had forgotten about it.
Funny, I just rewatched the BB cartel murder episode last night. I had forgotten (until I read it recently) that Gus had used that same tequila.
Solid reasoning. Why Omaha though? Why not still in Albuquerque?
Saul has to believe that Lalo is still alive. Gus must kill him in the unfinished lab.
Here is a question. Does Lalo come after Kim/Saul just because of the situation in the desert with the bail money? Last season, he is still not sure of what happened after visiting Kim and Saul. What has convinced him since then?
Agree that it might have been symbolic, possibly even the end of Kim and Saul's relationship, as the bottle top was just laying by the curb. The thing that still nags at me as why the clerk said to be careful with the top its sharp. That was just so oddly specific.
