Apollo

Description
Apollo, The father of the Days, and husband to Their mother, was first debuted in the episode Regret. Currently, the only image of Apollo is that of him at his murder with an unrecognizable visage. In INTERROGATION, Apollo is revealed to have been friends with John and He and was the one who entrusted Maggie to John. Apollo's death ends up as a major catalyst to the plot as Tues Day's primary motivation is to attempt to resurrect him.

Theories
One of the largest mysteries existing in the tcu is that of Apollo's murderer. Speculation has emerged but no leading theory has persisted.


 * John: John is known to be morally disagreeable and it is known he own a gun. There is little motivation present for why John would kill Apollo, but if there was it could explain John's determination to stop Tues Day.
 * Joshua: Joshua is known to own a gun and even has been confirmed to have shot people out in the streets, which is where Apollo dies. Joshua has no confirmed connections to Apollo other than through Thurs Day and Fri Day, so no motive is known.
 * Fergus: It is established in Regret and INTERROGATION that Fergus and John had some event happen that split them up. Some speculation states that the event could have been the death of Apollo, which would likely mean Fergus was the murderer. Again, motives are very unclear, and this would mean John would have found out, which goes against what Wednes Day states in Regret about there being not enough evidence.
