Six times Quake helped his brothers and the one time they helped him

Hali: Quake helped him move on from his childhood trauma of nearly killing his brothers

Tau: Quake was there to remind him that he doesn't need to fake a smile all the time

Blaze: Quake helped him through his nightly strolls, reminding him that it was not his fault

Ais: Quake helped him realize that being fat doesn't hinder his ability, and that it doesn't make 

him ugly or weak

Thorn: Quake reminds him that he wasn't the weakest one among them: none of them are. 

Quake helped him realize his own importance

Solar: Quake helped him through Retak'ka's trauma, and was there for him when he feels left out by the rest of his brothers

They all didn't realize that Quake was suffering as well, taking all the burdens of his brothers

He had been focused on their problems that he had been neglecting his own

His brothers are moving on with their lives

And now Quake couldn't ignore his problems

It all came crashing down on him

But Quake being Quake, he put up a strong front

But it was all killing him on the inside

The others found out on Quake's moment of weakness

When Quake was about to pull the trigger of the gun against his head

And at that moment, Quake broke down

And the others promised that they will always be there for him

That he need not carry all the burdens by himself
