Like Brother Like Sister 2

After drawing a pic of Berlin and Amy showing brotherly/sisterly love for each other, I thought about joining Russet and Tammy with a family-like relationship towards real SEGA characters. Here's Russet with Knuckles watching the Master Emerald together. Although Russet enjoys looking at fine jewelry, she's not obsessive into it like Rouge is. They don't plan to marry, but Knuckles knows how kind and considerate Russet is compared to Russet's cousin.
