Reichu: Apparently, Shinji didn't take too well to hearing from his father again.
Shin-seiki: I actually laughed my ass off the first time I noticed (only after watching this episode several times) that Shinji had ripped up the letter from his dad, then taped the pieces back together.
Keisuke-kun: Why is that stuff all scratched out in black?
Shin-seiki: My take is that Gendo's secretary or someone had prolly typed up a polite, over-elaborate form letter, and Gendo blacked out the text and just wrote with a marker, “COME!- Gendo Ikari.”
Reichu: So succinct. Typical Gendo. (BTW, koi is the imperative form of kuru, "come".)
OMF: I love how Shinji furiously scribbled over Gendou's handwriting, as well.
Shin-seiki: It was Misato's photo that seemed to have changed Shinji's mind about coming, hence the necessity of taping up Gendo's letter…
