This was Harry's worst nightmare becoming reality.

He had not returned to Hogwarts for his seventh year for many reasons. The Horcruxes, being the main one. But also because him being there would put everyone he cared about in danger. But after almost a year of staying away, it was ruined. He was back at Hogwarts, and a wizarding war had broken out. One that would changed wizarding mankind forever.

Of course, Harry knew that he had to protect himself because that would ultimately destroy Voldemort, but his friends' lives were perishing before his eyes and he couldn't stand it. Especially when he caught sight of the evil Bellatrix Lestrange about to attack Molly Weasley, the person who has been like a mother to Harry.

"PRO-" Harry was about to cast the shielding charm over her, but it looked like she was perfectly capable of handling herself. She had killed Bellatrix. A mixture of shock and relief overflowed him, but it didn't stop him from being concerned. Now death eaters were flocking her with attacks.

"PROTEGO!" Harry cast on Molly Weasley. But she had to get out of there now, because the shielding charm could not block the killing curse.
