Cole and Zeke have an epically bromanticscene on the new rooftop. After chugging all the beer they've got and falling asleep on the couch, they end up with their heads on each others' shoulders. When Cole wakes up, he casually uses his new blast core while Zeke is still passed out, comically flopping down out of sight behind the couch when it's done giving him a new power.
The punchline; Zeke and Cole agreeing the whole thing was a great way to spend an afternoon.
Zeke: Damn man, Kuo never told us this town was overrun by a pack of inbred, shirtless crocodile freaks. Cole: I know. It's pretty cool, right? Zeke: Oh-ho-ho, completely. Totally makes up for the Militia being here.
If you decide to take the evil route on your way into New Marais, Kuo is understandably upset when you overcharge a generator near the bridge, killing both enemies and innocents. She goes all What the Hell, Hero? Cue Zeke's voice in your earpiece: "Things... uh... tend to blow up around him. You get used to it."
One of the side missions in two involves tampering with TV dishes so Zeke can put his own program on the air. What program does Zeke show? A dating video for Cole.
Zeke: He loves all the standard crap. Long walks on the beach, brushing ladies' hair, romantic picnics with cheese.
Heartwarming and funny: Cole comforts Kuo in his own way when she's scared and disgusted by her powers. The cherry is how Kuo sounds both touched and a little taken aback by Cole's hilariously crude phrasing.
Cole: Listen, Kuo, you're not a freak. You're still you. You just happen to have ice coming out of your ass.
At the end of festival of blood, when the woman Zeke was courting flashes a pair of fangs at him, Zeke's reaction is a simple but priceless "OH SHIT!" The look on his face, lacking his sunglasses, seals the deal.
Or shortly before the above sequence, when Cole enters the bar and needs Zeke's help. He dropped his weapon in a swimming pool and can't get it out...
Cole's taunts to the Behemoth when he first fights it
Cole: PUCKER UP, BITCH!!
There is a mission where Kuo has been kidnapped by the Militia. There is the Good option to release a small army of captured police to held you attack the Militia base, and then there's Nix's idea of loading a tram up with explosives and just blowing a hole in the front of the building. If you take the Evil option, Cole asks for Nix's help saving Kuo, but she suggests just leaving her while they have fun fighting the Militia. Nix had no idea why they were even attacking the place; she just wanted to blow them up!
