I think that the waste mart man will go looking for Viji, Rukku, Muthu, and Arul again. Based on the text, the waste mart man went looking for them and found them under the bridge. He was mad that they got away so he wanted to catch them. Usually when someone is that determined to find out where someone lives, it means they probably won’t stop untill they suceed.
I agree with you, Amaya, but I don’t think he’ll look for them immediately.
I don’t think that he will keep chasing them because he would have to search the whole city and don’t think that he wants to do that.
