When Abuela came wandering out looking for Felipe I was kind of confused about her presence but then was impressed with the respect the men showed to her as she interrupted a very intense standoff. I assumed they would consider her an annoying pain in the butt, but instead they were very attentive and respectful toward her and finally, on Abuela's gentle insistence, backed down led their "enemies" straight into their safe house.
What a surprise to find they were protecting helpless elderly nursing home patients who had been abandoned by the staff who had either been killed or ran away! I felt that Guillermo and Felipe must be earth angels or saints or something to that effect to be so compassionate and caring to sacrifice their lives to care for and protect the lives of these elderly patients. They could have escaped with the other employees, but chose to stay instead.
I don't know if I would have done the same thing.
