Question: If Callaghan knew that his daughter was dead because of project silent sparrow, how did he attended the SFIT students showcase happily? And after the fire at SFIT, everyone presumed that Callaghan was dead. So when did Callaghan visit the project silent sparrow to know that his daughter was dead, before or after the fire?
Answer: I think the fire was his original revenge plot but the microbots provided a chance for an even more satisfying end to Krei. Likely Abigail disappeared a year or two before (judging by how the men hardly aged) and Krei had to rebuild his company's image therefore creating the event. The comeback would have been hard on Callaghan and may have caused him to plan the fire and his death in the explosion assuming KreiTech couldn't recover from both, perhaps even would have taken Krei with him. But then he the microbots changed everything.
Question: At one point, Aunt Cass mentions an 80-year-old woman wearing something inappropriate for her age. What exactly is Aunt Cass implying there? What kind of outfit is she suggesting the old woman is wearing?
Chosen answer: Something that is probably showing a lot of skin. Something someone in their teens or early twenties would be seen wearing.
Question: SPOILER: It's shown in the movie that Hiro was sad about Tadashi's death for few weeks, and Abagail (Pr. Callahan's daughter) was lost in the second dimension before the fire in the science fair, so how is Abagail still alive after all that time?
Answer: Baymax said that 'the patient' was put into 'hyper sleep' which is almost like a coma.
Chosen answer: The Silent Sparrow incident took place long before the events of the film. He had been plotting his revenge for some time, part of which was using the fire to steal the microbots.
