I can't place this as the last line in B's Init method (obviously, because I don't want to repeat lines in A's Init method), but I need to execute A's parent class Init method codes...

Add a property to Class A, that would show you what part of code you should execute in Init event:

Line 1
Line 2
.
.
.
IF this.SomeProperty
   Line 10  for YourClass B  <-- (my subclass need a diff code for this line)
ELSE
   Line 10  Normal Line 10
ENDIF

.
.
.
DODEFAULT()

Other Way, I don't like it because if you change something in Init of Class A you SHOULD change the same thing in Class B:
Copy and paste Init from Class A into Init of Class B:

Line 1
Line 2
.
.
.
Line 10  for YourClass B  <-- (my subclass need a diff code for this line)
.
.
.
