She made her way down the cracked stone path, the sound of traffic fading as she neared the church doors. It took her several moments to peel the glamour of the Institute this time. It felt as if another layer of disguise had been added to the old cathedral, like a new coat of paint. Scraping it of with her mind felt hard, even painful. Finally, it was gone and she could see the church as it was. The high wooden doors gleamed as if they’d just been polished.
There was a strange smell in the air, like ozone and burning. With a frown, she put her
hand to the knob. I am Clary Morgenstern, one of the Nephilim, and I ask entrance to the Institute—

Clary Morgenstern since when? Yes, that is her father’s name, but the name on her birth certificate is Clarrisa Fray, not Morgenstern. I could understand if the wards around the Insitute can only recognize you by your name. However, it’s not even the case. The wards recognize and respond to anyone with Shadowhunter to blood.
Just because Valentine is her father doesn’t mean she has to take on his last name. In my opinion, that way of thinking is a bit old-fashioned. So story time, much like Clary I never really knew my real father. Oh, I saw him a couple of times, but I never had a real relationship. My mother and my biological father never got married and when I was born she gave me her surname.
My biological father and I have very two different last names (and thank god because my bio dad was such a goddamn loser)!
Back to the story: So why would Clary take on his name now, especially when her and Valentine’s relationship is far from warm and fuzzy? Now, this is speculation on my part and there has not been any real confirmation of this. However, I really feel that Clary wants to claim the name. For her protestations about how evil Valentine is, he still comes from a seemingly prestigious weathy family. He’s old money, and Clary wants to claim that prestige for herself to make her look good.
Now, again, I might be thinking too much into this, but I find it very werid that she’s claiming Valentine all of sudden.
