I is for Ike ('Limitless'), Ivy ('Gotham') and Indra ('The 100')

There aren't many "I" characters, and the ones we have here are mostly secondary, but they're interesting.

On Limitless, we've got Agent Ike (Tom Degnan), who is one of the FBI agents who is supposed to keep Brian Finch in line. Ike (probably) isn't his real name. We never actually know his name. Brian just likes to call his two babysitters Mike and Ike in order to identify them.

On Gotham, Ivy "Pamela" Pepper (Clare Foley) is a little red-headed delinquent girl who likes to pick pockets and trick people out of their money. She's a little bit nuts, but in a very humorous way.

Finally, on The 100, Indra (Adina Porter) is one of the Grounders. She used to be considered one of the "bad guys," but she just wants to protect her people from the sky people. She's loyal, and later forms a bond with both Octavia and Kane from "skaikru."
