Lopez fits right in with Chaske Spencer, Alex Meraz, Kiowa Gordon and Bronson Pelletier.
In a sit-down interview with "Extra," Pelletier -- who is nicknamed "Slater Jr." -- joked to Lopez that, "when we were casting this thing I thought I was gonna lose my role out to you."
Added Meraz, "You're the missing wolf pack member!"
Taylor Lautner says it's "definitely a possibility" that Lopez could join the pack. Stewart was more sure. "You totally could be," she said.
"We'll get you in there," Spencer promised.
