On the page mentioned above, there is a list of interactions we have with Alduin (don't read all of it, only the 'Sovngarde' section):
Interactions
Unbound
During the executions, Alduin will be flying above Helgen, and his roars can be faintly heard. Once the Last Dragonborn is placed on the chopping block, he will land on top of the tower above and use the roar that summons a storm raining meteors down from the sky to cause havoc and destruction in the settlement. During the Dragonborn's escape from the village and into Helgen Keep, he will be seen fighting a number of Imperial soldiers, and may land and attack the Dragonborn in front of the keep if the Dragonborn does not escape quickly enough. Once the keep is escaped through the cave, he will be seen flying above, and will fly away to the east.
A Blade in the Dark
The Last Dragonborn and Delphine both travel to Kynesgrove during this quest. Here is where Delphine has predicted that the next Dragon will be resurrected. It turns out Delphine is right and here, on a dragon burial mound, Alduin can be seen flying above. A blue light is rising out of the mound. Alduin will use a shout to resurrect this dragon. He speaks the words "Slen Tiid Vok!" and a shout that looks similar to Unrelenting Force will go into the mound, causing the stone lid to crumble and burst apart. A skeletal dragon will then rise from the mound and start speaking to Alduin. After a small conversation between the two dragons, the skeletal dragon will regain his scales. This dragon is known as Sahloknir. They will then notice the Dragonborn, at which point Alduin taunts the Dragonborn on their lack of knowledge of the Thu'um, before ordering Sahloknir to kill both the Dragonborn and Delphine before taking his leave.
Alduin's Bane
In the vision of the past seen through the Time Wound, three heroes known as Felldir the Old, Gormlaith Golden-Hilt, and Hakon One-Eye are seen fighting off the dragons. Gormlaith will kill a dragon whom lands by jumping on to it and then stabbing it in the head. Afterwards the heroes will discuss the possible use of an Elder Scroll to defeat Alduin, but Hakon says it is to dangerous. Alduin will come down to fight them and then the three heroes will use Dragonrend to bring down Alduin. Alduin will then engage in combat with the three heroes. Gormlaith will be killed by Alduin and then Hakon will tell Felldir to use the Elder Scroll. Alduin will continue to fight Hakon for a short time before noticing what Felldir is doing. Alduin will turn to Felldir and try burning him with Fire Breath, but this does not work and Alduin is sent forward in time.
Upon awaking from the vision, Paarthurnax will say that he hopes the vision told the Dragonborn what he needed to know because Alduin has arrived. Alduin taunts the Dragonborn that their time is up and once he kills them, their soul will feed his hunger in the afterlife, only for Paarthurnax to retort that he is too late. The two brothers exchange words as they engage in battle in the skies. Alduin will start the battle by roaring and summoning a storm that rains meteors down from the sky. The only way to damage Alduin is to use the Dragonrend shout. Upon Alduin's defeat, Alduin will fly away to Sovngarde.
Sovngarde
Upon entering Sovngarde, Alduin can be seen flying around in the back. He will occasionally swoop down to pick up a soul in Sovngarde. The Dragonborn must travel through the mist that Alduin has set up until they reach the Hall of Shor. Here the three heroes will again come out to fight Alduin, although this time they have the Dragonborn to help them win. Before the battle can begin, the Dragonborn and the three heroes must disperse the mist that covers the land. They use Clear Skies to get rid of the mist, but Alduin will make the mist reappear. This process must be repeated a few times before finally Alduin will come out and battle. After killing Alduin, the Dragonborn will not absorb his soul. Instead, Alduin explodes after yelling words in the dragon language that, when translated, indicate his defiant refusal to believe he can truly be slain.
In my opinion the Sovngarde section should be replaced with the following sections:

I wanted to edit the page myself, but I am not sure I know who to do it properly, so I wrote this post for the Moderators and Administrators to edit the page themselves, if they would find this edit fitting.
