Steven Universe - Oh and Connie's totally cool with Lapis because (???), so there's that.

In response to the title, keep in mind that every gem Steven has currently met has tried to murder him on at least one occasion. I mean Peridot pushed Greg off a roof and he just brushed it off like a champ. If Connie is going be part of the Universe family one day she's going to have to learn to roll with the punches.

Peridot: "Well, isn't this quite the combination of secondary characters!"
