Shakespeare uses a couple techniques to show the conflict between Hamlet and Gertrude in this scene, irony being the one most used.
First, Hamlet speaks in an aside (meaning no one else can hear him) to indicate he's not interested in speaking to his family -- they are "less than kind."
Then, Gertrude comments on Hamlet's clothing, indicating he's mourning too much. She tells him directly to be kind to Claudius. She says people die all the time, and he replies "aye, it is common," an ironic reply. The death of a king is not "common" -- nor is murder.
Then, Hamlet discusses the meaning of the word "seem," implying that people could fake their grief. (He's implying, perhaps, that Gertrude faked her grief.) His grief, however, IS real.
Watch for danger or death
It intensifies the conflict.
A complication adds to the problem of the story. The stories problem is the conflict. Many times there is more than one complication. When labeling a plot line for a story, the complications can be found in the rising action. This takes place between the exposition and the climax. The exposition of a story introduces the characters, setting, and conflict. The climax is the pivotal point in the conflict. The character can never return to the way things were when the story started out. Something or someone has been irrevocably changed.
It could be considered many things such as Fantasy, Greek Mythology, but if memory serves me correct it is simply called an "Epic" because it centers around Heroes and Monsters.
