Found this randomly growing in my (admittedly poorly maintained) garden. Is it poison ivy? I brushed my fingers over it because I was wondering if it was connected to another plant before realizing it might be poison ivy and dropping it. The darker, smaller leaves in between the spiky ones in the second pic are my tomato plants. How fucked am I?

EDIT: Lol I'm dumb, it's just a blackberry vine reaching veeeery far from where it was planted. Consider this one solved!
