Inflagrante, InSergio, same thing right? LOL 
InSergio = Latin for I am doing it with Sergio
Now if I remember from school:
inSergio = I am doing it with Sergio
inSergias = you are doing it with Sergio
inSergiat = he is doing it with Sergio
inSergiamus = we are are doing with Sergio
inSergiatis = you (more than one) are doing it with Sergio
inSergiant = they are doing it with Sergio
Thanks for the refresher David!
