Answer:
This passage describes the effects of Telemachu's return on Eumaeus and how he felt even when it was an irony for him to be happy.
Step-by-step explanation:
First of all, we need to understand one thing, there is a very bad past between both and it hurts both of them equally. But it is an irony because the fact that it hurts is Eumaeus fault, due to his actions and their effect on Telemachu's life. So even though Eumaeus feels happy it is an irony because he caused bad effects on his son's life.
