Does my crush like this other girl?

Our group hung out last night and one guy in our group (my crush) invited his female friend (who is in town now) to join us. We had some drinks out. When we all were heading home he joked with her and kinda tickled her waist. Further ahead she said ”Well this is where I leave you” cause we had reached her hotel. Our guy friend went to her and gave her a long hug. I heard her say ”Text me tomorrow if you wanna hang out”. He replied ”absolutely”.

Was this flirty? Do any of them seem to like the other as more than a friend? Does he like her?
