One should never admit to this in a review, but I don't have the brains to restrain myself at the moment. I sort of, um, skimmed bits of this, so I'll have to come back and reread. There were moments of melodramatic romantic angst toward the end that prickled at me, but I'm a finicky reader, and it's all cushioned in wonderfully coherent writing. I liked especially the dry, slightly humorous tone to Snape's perspective (The man did not just say, after storming Harry's MoM birthday celebration, that he prided himself on his calm demeanor. Surely, that is just a case of excess beeswax on my part? Or maybe I underestimate the pregnant male's power of self-delusion).
Don't give him a choice, my boy. - Mm, excellent scene with Pomfrey that segues smoothly into the succession of caretaker!Harry and bedridden!Snape ones. Clever ploy to throw them together and kind of mirrors their relationship rather well: oh-so-careful, stepping-on-eggshells Harry who needs to care and vulnerable, grouchy Snape who hates his own helplessness. I might be reading too much into it, but it seems to set up the relationship nicely.
"Your spawn hates me, Potter." - Ooo, my favorite sparkly line! Classic snarky Snape through and through; pregnant through Harry's typical botched ideas and doubly miserable because of it, how could he not take this shot? It's THE Snape line for me. :D
I'm sure I had more to say, but again, I will be rereading, so I'll save the rest of my senseless blather till then.
