What is it that draws Derry towards Mr Lamb inspite of himself?" in two or three lines

In which section of the play does Mr Lamb display signs of loneliness and disappointment? What are the ways in which Mr Lamb tries to overcome these feelings?...in two to three lines

Will Derry get back to his old seclusion or will Mr Lamb’s brief association effect a change in the kind of life he will lead in the future?

Mr Lamb tries to guess the cause behind his burnt face. Derry reveals that one side of his face was burnt due to exposure to acid, and it will remain the same forever. Derry finds Mr Lamb’s composed reaction to this piece of information a bit odd. He asks Mr Lamb astonishingly if he is not interested in it. The latter reasons that everything created by God is interesting. Every living thing is the same no matter what. Mr Lamb talks about how he has a tin leg and kids call him ‘Lamey-Lamb’. Some people notice and talk about his tin leg, while some do not. But it does not bother him. Mr Lamb tries to compare this phenomenon to the fairy tale of ‘Beauty and the Beast’.

Answer: Derry, a complex-stricken lad of fourteen, is a victim of inferiority complex which is borne out of a misinterpretation of himself and the world. He suffers from an acute sense of self-hatred and rejection due to his burnt face and this leads him to total alienation.
