Alma is pregnant with Blacksad's baby.When we see Alma alone on the Niagara Falls trip there's a subtle panel of her with her hand over her abdomen and she has a sullen look on her face. Now the look could be attributed simply to her disappointment that Blacksad wasn't there for her. But the hand on the abdomen seems to me like a masterfully subtle hint that Alma's carrying Blacksad's baby. I apologize if this is dealt with in the fourth album (I haven't read it yet).
The lynx from Red Soul is related to Blacksad.... a speculation based on the fact that Blacksad’s kid nephew has a russet-and-white fur (like the lynx) rather than the black-and-white fur of his mother and uncle.
