Two ways of dealing with tear gas grenades from comrades in Turkey: Either submerge them in water. Make sure you can close off the container cause the gas will still spread for a while. Or throw them in the fire so the gas burns off before it can spread.
[[I think that the one person Sirius could have loved was James. Sirius talks so much about James in canon and he was the first person who really accepted him for who he was. Sirius loved James enough to want him to be happy with Lily and couldn’t hate her because of this. James probably realised that Sirius fancied him but didn’t make a big deal out of it because he didn’t want to lose him as a friend. I can’t imagine how awful it must have been for Sirius when James died. 12 years of hell.]]
