In MMA class a guy saw a bruise on me & joked that he’d get the culprit. was he flirting?

I’ve been training a year and have seen this guy around but don’t really know him. He’s been training 10+ years so is very experienced. Today he picked me to roll with at one point. Then at the end of the class he saw a bruise on my leg and joked that next class he’d get the person that did that to me (like, in a roll at the gym kinda way). It kinda felt like he was flirting…or maybe just being protective of a less experienced girl at the gym. Thoughts?

Edit. I’ve actually not seen him at all since then…. turns out he was travelling in Asia for a couple of months. With his girlfriend 😆 oh well.
