Is my friend just wanting to hookup before he leaves?

[Lilmisus]

For the past two months I've been working with this guy who I've become friends with. Not necessarily close, but close enough to hang out three times outside of work with others and close enough to get love advice from him a couple times. He's become one of my favorite coworkers since he's awesome to talk to and fun to be around.

 

The last time him and I hung out (with three others), we went to the beach and two of my friends and I left shortly after because it was starting to storm. Him and his friend wanted to stay, and since he didn't have a towel, I let him hold onto the two towels that he was lying on but asked that he give them back to me the next time we saw each other at work (the next day), but of course, he never gave them back.

 

Fast forward to tonight. I find out that tonight was his last night at our job since he's moving back to his hometown in a week or so, with no intention to come back here to the beach. Of course finding out saddened me, but I was not letting go of my towels (I always remind him, typically just joking around), I tell him that he needs to give them back to me before he leaves, so that he should stop by our job tomorrow or sometime this week and hand them over. He said that we could just hang out again and he can give them to me then, to which I say "sure! I'm hanging out with (close friend/coworker) Wednesday, you can come too." But...apparently he meant one on one "hangout" though didn't elaborate on it, since he basically said "Oh, I meant just us, you don't want to hangout with just me?" I just laughed that off though (though he wasn't trying to be funny), and we basically now have plans for Wednesday, and will prob try to hang out again before he leaves.

 

This guy has flirted with me for a majority of the time that we've worked together, and has tried hanging out "one on one" more than once, but I've never thought too much of it. Especially since he was going after my friend for the first few weeks that I knew him. I have plenty of guy friends who I'm fine with hanging out with just them, but the way he phrased it, gave me a weird vibe. Maybe it's just me over-analyzing things as I do, but I'm just wondering if I'm alone in thinking that he was or is looking to hookup with me by trying to hang out with just the two of us (rather than us with OTHER friends that he most likely wont ever see again as well)? I'm not going to let it get in the way of our friendship or plans, but should I just stay on my toes, especially since I'm not planning on going down that path with him and don't want anything like that ruin our friendship?
