Oh dude! Dont worry about how it looks to others first off, when she pulled away with you the group knew what was up. I like day game better myself anyway. Now I've spent a few years in europe with the language barrier thing, and I've learned that using your hands is a great way to communicate, (kino in PUA terms) and with foreigners, touching is way more accepted than it is here in the states during normal interactions outside "night game time". In this case, use your hands to help indicate you like her but your time is short, by taking and squeezing her hands but then tapping your watch with her hand (cheesy but it worked for me), while saying you really wanna talk more but you have to go. Then just ask her number and try to get back with her later that day. The fact that she was trying to understand meant you coulda screwed it up 9 ways to hell and still got her man, when theres a language barrier, people are more forgiving.
