In S06E01, we see Lalo going to a couple's home after the events of last season.
It seems the couple knows Lalo and offered him coffee and talks with him about how he helped the family. And then we see Lalo catching the scissors as if to kill the woman, but it is not shown, and then it cuts to him going to the bathroom where the women's husband is shaving his beard and he sees him, both laugh and it cuts again. Nothing is shown about them afterward.
So did Lalo kill them? If so why when he helped them so much?
