Someone wanted $1.20 on a 100 shares

that was strange

bid was 1.11

ask was 1.20 on a 100 shares only

the 1.20 went through and the ask went back to 1.50

then a big spender come in and bought 5 shares at 1.50

but again the last price was 1.50 ( last trade ) although the ticker still shows 1.20

im lost with what direction this is possibly going in as the daily trades make absolutely no sense at all
