I'm really confused. Did Grisha apparently get the power from Kruger, named his son after him, then gave Eren the power, (and as I recall from a past chapter) he ate his father ?
Yes. Morbid isn’t it? Yams certainly has an interesting sense of humor.
I think one of the best things about this chapter was finding out that Grisha chose to name his son after Eren Kruger - the man who beat him as a child and was culpable in the deaths of Fay, Dina and all of Grisha’s friends and compatriots.
I do think when Eren was born, Grisha felt nothing but gratitude towards Kruger for giving him a second chance, even though that second chance meant cursing him with a life-ending mission.
