Buffy didn't know what Sam was saying, but she was pretty sure it was Latin. All foreign languages ended up sounding the same to her, though. Sam wasn't a wiccan to her knowledge. She wished for Willow - she could count on her and she had worked with Willow for so long they understood how each worked. Buffy and Sam had never worked together, they didn't know how the other operated. They just had to improvise and hope for some of that crazy stuff called blind luck.
Luck seemed to attainable. Buffy felt the pain on her leg remove from feeling like an internal pain. The smoke was drawn together and made corporeal - a real form. An ugly bastard, to tell the truth. A slim-faced demon with brown skin the texture of course sand. The demon seemed surprised to have been made into real form, but its' hand remained on Buffy's calf. Turning around to see her attacker, Buffy groaned at how gross the demon was. There was probably going to be a slime factor.
She wasted no time in grabbing for the metal towel rack on the wall, scrambling to her feet. The rack ripped away from the bad paintjob, cracking the wall. Buffy twisted her torso around as she thrust one end of the metal bar forward. The demon caught it. But it was no problem for Buffy.
On the other side of the door, which still wouldn't open, Sam would hear a fight going on - no words, just bodies slamming against the sink, throwing punches, breaking everything in sight to obtain the coveted upper hand. It was easy for Buffy, and she didn't even think to open the door to let Sam help. Buffy was used to working on her own. Her reflexes were sharp, and now that she could actually fight this demon, she wasn't worried.
The confidence she wore on her face seemed to help intimidate her opponent. With a few more crashes, everything was silent on Buffy's side of the door. Several moments passed before the door swung open, Buffy in the foreground - hair messy and wet, body wrapped in a towel. Behind her the demon lay belly-up, the towel rod stuck in his gut. Blue blood pooled from the wound. Aside from a raked claw scratch on her leg, there was no evidence from Buffy to indicate she'd taken part in the fight.
"Gotta love the welcoming parties," she practically sung while sashaying out of the bathroom.
