Raiden finally reached the house after leading the huge horde of the zombies far away from the house.
He got off his bike and entered the house. All the time while he was leading the zombies away from the house, he just had one thing in his.
'Are they still alive?'
The 4 who he left inside the house were trapped inside the house all this time, trying to survive from the zombies. He did not know if they were alive or not. Seeing the huge amount of horde that invaded the house, he wasn't sure anymore if they would be alive or not.
That's why he immediately grabbed all the attention of the zombies so even if there was a slight chance of their survival, he wouldn't wanna miss it.
He finally returned from doing what fit best to him.
He saw the giant hole in the entrance of the house but he didn't care. He moved in and started moving along the corridor.
