Rob grows frustrated with his driver, whom he believes to be making inadequate efforts to stay close to Tyler and James. "What are you waiting for, bro?" he wonders. I can't think that calling your cab driver "bro" is a promising strategy when you've determined that he barely speaks English. Throwing in the random syllable at the end of the semi-rhetorical question? That's just going to confuse everyone. Kimberly tries to keep him calm. Rob explicitly threatens to freak out; she says she'd rather do without the freaking out, actually. The Pointy driver does lose track of the boys, though, and the boys take note that they are no longer being followed. It appears that Rob and Kimberly now have no idea where they're going at all, and she thinks it might be better to just bag on their cab and go back. Ouch. So they left with nothing but following. That isn't smart.
The *wins and Tom and Terry are getting to the park at last, followed by a trailing Dave and Mary. Mary is working on her Vietnamese with her driver, and she finally pauses and says, "I like you!" "You ain't taking him home," Dave deadpans. "I love him! He's so cool!" Mary says enthusiastically. She is super-excited. It's either a refreshing lack of xenophobia or a honkload of caffeine. It's true that Mary verges on wanting to keep people from other countries as adorable pets, but for the moment, she's okay with me. Mary is very excited to see the *wins up ahead, approaching the park. When she and Dave get out to listen for the clue, she forces a little awkward hug on her driver. I tolerate that better when it's out of an explosion of enthusiasm the way it is from her, but really, Mary...not everybody likes hugs from strangers. Boundaries!
