Baldur's Gate 3 - What Happens If You Have No Allies For The Final Battle?

Thou art alone. Didst thou not make allies?

Showing the cutscenes that play at High Hall when you don't any recruit allies for the Gather Your Allies quest. 

0:00 Only party allies
1:46 No allies at all

There are two variations. The first is when the only allies you have are your party members. As seen in this video, Ascended Astarion, Halsin and Jaheira still give words of encouragement. The second possibility is having absolutely no allies at all. In this case, Withers warns you about the difficulties ahead. In both cases, Beorn Wunterbrood, the Flaming Fist who usually speaks to the gathered allies, will be dead.

The flag for the first situation is END_GatherYourAllies_State_OnlyPartyAllies while the flag for the second situation is END_GatherYourAllies_State_NoAlliesPresent. I had a hard time triggering the latter, so I used the following console command to enable the NoAlliesPresent flag:

Osi.SetFlag("fce77c88-3045-4292-9028-079c391d5a19", GetHostCharacter(), 1, 1);

@bouch_ did manage to trigger the NoAlliesPresent cutscene in his 0 stat challenge run:
