After months and months of rumors, Peter Capaldi has announced that the 2017 Christmas special will be his last episode as the Twelfth Doctor. Although his departure is all the way out in December — and there's a nice new season with his Doctor scheduled to premiere on April 15th — Whovians around the world are already in mourning.

It feels too soon to say goodbye, and yet before we know it, someone else will be piloting the TARDIS through time and space. There's already a flurry of speculation surrounding the next choice to play the Doctor, but that new actor's time will come soon enough. For now, let's focus on everything Capaldi brought to the show as the irascible and unforgettable Twelfth Doctor.

4. His Temper

There's no denying the Twelfth Doctor has had a shorter fuse than some of his modern counterparts. While this made for a somewhat rocky transition after the happy-go-lucky attitude of the Eleventh Doctor, Capaldi's fire-breathing, eyebrow-glaring incarnation of the Time Lord was definitely an interesting change. Twelve was far more volatile and dangerous than what has typically been portrayed in the modern series, but it also made for a Doctor who will be absolutely unforgettable.

3. His Flare For The Dramatic

No matter where in time and space he was, Twelve had the distinct talent of ensuring all eyes were on him at all times. It helped that Capaldi was already a natural showman. No matter who is cast as the next Doctor, it will be hard to top the wildly insane yet brilliant ways this particular incarnation would find of leaving his mark on the universe, from using a spoon to duel with Robin Hood to playing the electric guitar atop a tank in 12th-century England.

2. His Kindness

It might seem paradoxical to refer to the Twelfth Doctor as kind when we earlier mentioned his temper, but the truth is that deep underneath the crabbiness and biting wit was a pair of hearts that never stopped caring deeply for his friends. He's short-tempered with idiots yet encouraging to those who show a true desire to learn and understand the universe around them. One minute he could be full of fire a range, living up to his title of "Oncoming Storm," the next, he could be showing forgiveness and mercy. Capaldi expertly navigated between these two extremes of the Doctor's personality, demonstrating the kindness that lay beneath the cold, alien exterior.

has made no secret of his love of . He started watching way back in 1963 when he was just 5 years old, and he is a veritable encyclopedia of Whovian lore. This irrepressible love of the show has bled through into his portrayal of the Doctor; the Doctor's passion for the universe is a reflection of Capaldi's passion for this character. He has an unsurpassed understanding of who the Doctor is and how he should be played, and his departure means the tragic loss of that remarkable insight.

We raise our sonic screwdrivers in salute to you, Peter Capaldi. Thank you for bringing the Doctor to life in a way we have never seen before.
