The young actor's sudden and tragic death came after his father passed away in May of this year, and following Angus' death, his co-stars paid tribute in his wake.
"I’m so grateful I got the chance to know him in this life, to call him a brother," Zendayawrote a day after the news broke. "To see his warm kind eyes and bright smile, or hear his infectious cackle of a laugh (I’m smiling now just thinking of it)."
"He was the sweetest and made everyone around him so happy," Maude Apatowwrote about Angus. "He was just the best. Words can’t really capture how magical of a person he was. My heart is broken."
"This is the hardest thing I've ever had to post, and I'm struggling to find all the words," Sydney Sweeneyposted. "You will be missed more than you know, but I'm so blessed to have known you in this lifetime, and I'm sure everyone who has ever met you feels the same."
At the time, Alexa Demie shared a heartbroken emoji against a black background to her IG Story.
Now, Alexa is breaking her silence on how she's been doing following Angus' death.
In a recent W Magazine interview about a Calvin Klein campaign she'd just shot, Alexa talked about how the experience of the gig was "light and fun" — and it sounds like it helped her grieve Angus' passing in her own way.
"I'm realizing that healing and processing does not look like one thing," she said.
"So right now, I'm trying to be light when I can."
