What should have happened in season 7X22

When Sylvie Brett decided to accompany Kelly Severide to Vegas, she didn't expect to wake up married to him. And when they decided to annul their marriage, she definitely didn't expect to become such good friends with him. But with Kelly's friendship she learns her place in 51, in Chicago, and how to be the person she wants to be.

Violet Casey, Matt's favourite (and only) niece points out what Matt had been so blind to; Gabby Dawson has the hots for him. While he is engaged. While Matt is most definitely... Shocked at this news, he is in no way pleased. As a result, they never get together.

But fate has other plans, and even if it doesn't seem like it, the universe is also keen to make people feel better. And in this case, the universe, God, coincidence, call it what you want, has sent a little girl mabye too silent.
